Marxist analysis points towards full collectivization of production and distribution globally, it isn't about communalization and decentralization. When I say “communalization,” I mean anarchists propose horizontalist, decentralized cells, similar to early humanity’s cooperative production but with more interconnection and modern tech. When I say collectivization, I mean the unification of all of humanity into one system, where production and distribution is planned collectively to satisfy the needs of everyone as best as possible.

For anarchists, collectivized society still seems to retain the state, as some anarchists conflate administration with the state as it represents a hierarchy. For Marxists, this focus on communalism creates inter-cell class distinctions, as each cell only truly owns their own means of production, giving rise to class distinctions and thus states in the future.

For Marxists, socialism must have a state, a state can only wither with respect to how far along it has come in collectivizing production and therefore eliminating class. All states are authoritarian, but we cannot get rid of the state without erasing the foundations of the state: class society, and to do so we must collectivize production and distribution globally. Socialist states, where the working class wields its authority against capitalists and fascists, are the means by which this collectivization can actually happen, and are fully in-line with Marx’s beliefs. Communism as a stateless, classless, moneyless society is only possible post-socialism.

Abolishing the state overnight would not create the kind of society Marxists advocate for advancing towards, and if anything, would result in the resumption of competition and the resurgance of capitalism if Marx and Engels predictions are correct.
