You might be saying no because the comment is facetious, but the transition state being capitalism and communist bliss (communal ownership and no state) is in fact the Dictatorship of the Proletariat, which is fully centralized authority. The real trouble with communism (and arguably socialism generally) is that reducing centralized control has proven difficult in practice… similar to what happened here.
Only according to Marx. Tons of socialists strongly disagree with Marx.
But even if they agree, the proletariat is not a few people.
The DoTP isn't necessarily supposed to be centralized state authority. Marx based his DoTP off the Paris Commune, which was the furthest thing from authoritarian.
