Anarchist communism advocates the abolition of the state, private property, and capitalism in favor of common ownership of the means of production, direct democracy and a horizontal network of voluntary associations, workers' councils, or a gift economy through which everyone will be free to satisfy their needs.

According to anarchist communists Peter Kropotkin and Murray Bookchin, the members of such a society would spontaneously perform all necessary labour because they would recognize the benefits of communal enterprise and mutual aid.[page needed] Kropotkin believed that private property was one of the causes of oppression and exploitation and called for its abolition, advocating instead common ownership, except where property-like personal possessions are used for oneself. According to Kropotkin, "peasant who is in possession of just the amount of land he can cultivate," and "a family inhabiting a house which affords them just enough space... considered necessary for that number of people" and the artisan "working with their own tools or handloom" would not be interfered with, arguing that "the landlord owes his riches to the poverty of the peasants, and the wealth of the capitalist comes from the same source."

Anarchist communism is also known as anarcho-communism, communist anarchism, or sometimes, "libertarian" communism. However, while all anarchist communists are libertarian communists, some "libertarian" communists, such as council communists and Luxemburgists, are not anarchists but are instead Libertarian Marxists. What distinguishes anarchist communism from other variants of "libertarian" communism is the former's opposition to all forms of political power, hierarchy and domination. However, some writers use "libertarian" communism and libertarian socialism as synonyms for anarchist communism or even anarchism in general.

Peter Kropotkin, often seen as the most important theorist of anarchist communism, outlined his economic ideas in The Conquest of Bread and Fields, Factories and Workshops. Kropotkin felt that co-operation is more beneficial than competition, arguing in Mutual Aid: A Factor of Evolution that this was illustrated in nature. He advocated the abolition of private property through the "expropriation of the whole of social wealth" by the people themselves, and for the economy to be co-ordinated through a horizontal network of voluntary associations where goods are distributed according to the physical needs of the individual, rather than according to labor. He further argued that these "needs," as society progressed, would not merely be physical needs but "as soon as his material wants are satisfied, other needs, of an artistic character, will thrust themselves forward the more ardently. Aims of life vary with each and every individual; and the more society is civilized, the more will individuality be developed, and the more will desires be varied."

He maintained that, in anarcho-communism:

...houses, fields, and factories will no longer be private property, and that they will belong to the commune or the nation and money, wages, and trade would be abolished.

– Peter Kropotkin, The Conquest of Bread

Individuals and groups would use and control whatever resources they needed, as the aim of anarchist communism was to place "the product reaped or manufactured at the disposal of all, leaving to each the liberty to consume them as he pleases in his own home." He supported the expropriation of property to ensure that everyone would have access to what they needed without being forced to sell their labour to get it.

We do not want to rob any one of his coat, but we wish to give to the workers all those things the lack of which makes them fall an easy prey to the exploiter, and we will do our utmost that none shall lack aught, that not a single man shall be forced to sell the strength of his right arm to obtain a bare subsistence for himself and his babes. This is what we mean when we talk of Expropriation...

– Peter Kropotkin, The Conquest of Bread

He said that a "peasant who is in possession of just the amount of land he can cultivate," and "a family inhabiting a house which affords them just enough space... considered necessary for that number of people" and the artisan "working with their own tools or handloom" would not be interfered with, arguing that " the landlord owes his riches to the poverty of the peasants, and the wealth of the capitalist comes from the same source."

While many anarcho-communists are opposed to trade, some post-left and post-scarcity anarcho-communists, and ones with syndicalist sympathies, are not opposed to trade. Some support a non-monetary form of trade in the form of non-monetary commons. Others such as Tiziana Terranova easily see anarcho-communism being compatible with a non-hierarchical, open access, free association, non-monetary form of trade such as P2P.

Economic theory

Anarcho-communism stresses egalitarianism and the abolition of social hierarchy and class distinctions that arise from unequal wealth distribution, as well as the abolition of private property and money. Replacing these approaches would be collective production and distribution of wealth by means of voluntary association. In anarchist communism, the state and private property would no longer exist. Each individual and group would be free to contribute to production and to satisfy their needs based on their own choice. Systems of production and distribution would be managed by their participants.

The abolition of wage labor is central to anarchist communism. With distribution of wealth being based on self-determined needs, people would be free to engage in whatever activities they found most fulfilling and would no longer have to engage in work for which they have neither the temperament nor the aptitude. Anarchist communists argue that there is no valid way of measuring the value of any one person's economic contributions because all wealth is a collective product of current and preceding generations. For instance, one could not measure the value of a factory worker's daily production without taking into account how transportation, food, water, shelter, relaxation, machine efficiency, emotional mood etc. contributed to their production. To truly give numerical economic value to anything, an overwhelming amount of externalities and contributing factors would need to be taken into account – especially current or past labor contributing to the ability to utilize future labor.

Anarchist communists argue that any economic system based on wage labor and private property requires a coercive state apparatus to enforce property rights and to maintain unequal economic relationships that inevitably arise from differences in wages or amount of property. They further argue that markets and systems of currency divide labor into classes and assign arbitrary numerical values to an individual's work and attempt to regulate production, consumption and distribution. They argue that money restricts an individual's ability to consume the products of their labor by limiting their intake with prices and wages. Anarchist communists recognize money as fundamentally quantitative in nature, rather than qualitative. They believe production should be a qualitative matter, and that consumption and distribution should be self-determined by each individual without arbitrary value assigned to labor, goods and services by others. In place of a market, most anarcho-communists support a currency-less gift economy where goods and services are produced by workers and distributed in community stores where everyone (including the workers who produced them) is essentially entitled to consume whatever they want or need as "payment" for their production of goods and services. A gift economy does not necessarily involve an immediate return (such as with remuneration); compensation comes in the form of whatever the person decides is of equal value to their products of labor (what is commonly called bartering). Any limits on production and distribution would be determined by the individuals within the groups involved, rather than by capitalist owners, investors, banks or other artificial market pressures.

Communist anarchism shares many traits with collectivist anarchism but has defining differences. Collectivist anarchism believes in collective ownership but communist anarchism negates the entire concept of ownership in favor of the concept of usage. Thus, things are seen as either private possessions used by an individual, or social possessions used to produce for society. Anarcho-communists believe that means of production should not be owned by any one person or entity, leaving it free to be used by individuals for their own self-determined needs and wants. Land and housing would no longer be subject to rent or property taxes (and therefore, its use would be free of eviction threats). It would instead be subject simply to the desires of occupants on an egalitarian basis. For example, in an apartment building in which many live, no one person would have a say in the arrangements. All who live there would be involved in decisionmaking. For example, occupants may decide to share certain responsibilities on a revolving-door basis rather than relegate them to a particular individual.

Crucially, the abstract relationship of "landlord" and "tenant" would no longer exist, for such titles are held to occur under conditional legal coercion and are not absolutely necessary to occupy buildings or spaces (intellectual property rights would also cease). In addition to believing rent and other fees are exploitative, anarcho-communists feel these are arbitrary pressures inducing people to carry out unrelated functions. For example, they question why one should have to work for 'X hours' a day to merely live somewhere. So instead of working conditionally for the sake of the wage earned, they believe in working directly for the objective at hand. From this it follows that, rather than land being for sale or rent, vacant land and housing would be freely taken regardless of one's employment or financial status (essentially, the "for sale" sign could be replaced by a "vacant" sign). Therefore, in anarcho-communist theory, land used by individuals for themselves or their families, or productive property used to produce for an individual (such as a small farm), would be considered private possessions rather than social possessions. The individual would be perfectly free to create something and keep it as long as it is not a crucial means of production for the community or general public. So an artist's paintbrushes would not need outside approval to be utilized, and the same basic principle would apply to other personal items such as one's toothbrush, musical instruments or book collection, which others needn't tamper with. However, if the matter at hand involves production for society (such as a factory which makes toothbrushes, musical instruments or books), it would become a social possession, accountable to all who work within it and the consuming public. In that regard, anarcho-communism could be considered a compromise between collective and individual use.[

Anarcho-communists reject mutualist economics because they believe that market competition, even non-capitalist markets, inherently create inequalities in wealth and land which would lead to inequalities of power - thus the recreation of the State and capitalism as some workers would have more access to capital and defence force than others. They reject collectivist economics arguing that remuneration would require a type of currency, which, again, anarcho-communists reject as an artificial measurement of the value of labor. They further argue that those who are not part of collective groups or unions in workers' councils and collectives could be alienated from access to capital, and thus promote free common use over ownership by society.

Philosophical arguments

Anarchist communists reject the claim that wage labor is necessary because people are by "nature" lazy and selfish. They point out that even the so-called "idle rich" sometimes find useful things to do despite having all their needs satisfied by the labour of others.[citation needed] Anarcho-communists generally do not agree with the belief in a pre-set 'human nature', arguing that human culture and behavior is very largely determined by socialization. Many, like Peter Kropotkin, also believe that human evolutionary tendency is for humans to cooperate with each other for mutual benefit and survival instead of existing as lone competitors.

Anarchist communists support communism as a means for ensuring the greatest freedom and well-being for everyone, rather than only the wealthy and powerful. In this sense, anarchist communism is a profoundly egalitarian philosophy. Anarchist communists do not think that anyone has the right to be anyone else's master, or 'boss' as this is a concept of capitalism and the state. Some contemporary anarchist communists and advocates of post-left anarchy such as Bob Black reject the concept of work altogether in favor of turning necessary subsistence tasks into voluntary free play.

Many anarcho-communists (and collectivist anarchists as well) reject "individualism" and "collectivism" as illusory concepts. They argue that an individual sacrificing themself for the "greater good" or being ruled by the "community" or "society" is not possible because society is composed of individuals rather than being a cohesive unit separate from the individual, and argue that collective control over the individual is tyrannical and un-anarchistic.
