I think that Marxism is not centralized - Capitalism is centralized and some communist implementations are centralized. Marxism, if anything, is distributed or communal.
It's not "nobody owns anything", it's "everybody owns everything". Maybe those mean the same thing to some people, but that's the idea.
Exactly this. Lenin's whole thing was to reach a point where the sate dissolves!
It drives me crazy how like 95% of HN is too scared or lazy to read a 10min wikipedia article on Marxism.
