I do not disagree with much of this, but for historical context it’s worth pointing out that, at least for Marx, Communism was a species of Anarchy. By definition therefore, the notion of a Communist state is an oxymoron. Furthermore, for most European socialists during the early 19th century, the notion of a Socialist society was predicated upon the absence of the state. The Marxist proposal of a Socialist state was widely regarded as a betrayal of said principals. (C.f. The critiques of Proudhon and Bakunin).
