It really is a hype based philosophy. I look at Marx as a bit of a stochastic terrorist of his time. His ideas aren't dangerous particularly taken with a grain of salt but because they are written to lead one to become angrier and angrier without being given an outlet to work towards things on a constructive way Communist communities start hopeful and sour over time.

He always dances around how that limiting of other classes authority and individual inequities is going to be handled because the answer... Is violence. A generous read is that he is naive to believe everyone will see he's right and kumbaya the whole thing into existence but more likely because of the language he uses other places he's flat out for the nessisary purge required to achieve his aims.

Issue being is anarchic mobs are generally fairly weak... So to make a successful change you basically need paramilitary leaderships and military like heirachy to achieve that purge... And then so far in history that paramilitary heirachy never has effectively dissolved after the fact because if everybody is doing communism correctly creating competeting heirachy is antithetical... You are just supposed to ignore that the paramilitary heirachy that becomes the state isn't strictly playing by Marx's rules either but by then a population isn't in a position to argue.
