The fundamental difference between anarcho-communists and anarcho-capitalists lies in their view of hierarchies in society. Anarcho-communists believe that anarchism aims to eliminate forced hierarchical authorities from society, whereas anarcho-capitalists argue that certain harmless hierarchies, like sports rankings, can coexist. Anarcho-communists reject the notion that capitalism is voluntary, stating that individuals are coerced to participate in the capitalist system or face dire consequences. They argue that capitalism does not represent a true choice and is inherently coercive, contrary to the belief of anarcho-capitalists who see capitalism as a mechanism to drive people to contribute to society through self-interest.
