So what you have to know about anarchy is that the vast, vast majority of unjust hierarchies are social constructs. Patriarchy, gender binary, whiteness, the state, neuronormativism, sanity, capitalism, religion.
These all exist in the mind. So to know the mind and understand it is to know hierarchy and to know anarchy. To be able to change your thoughts and those of others is to be capable of praxis. Materialism alone cannot create anarchy. Socialism, yes. But not communism. Communism comes from the power to destroy the shackles and weapons of the mind. This is chaotic anarchy, the anarchism of the psychonaut.
