So you never read what Marx wrote then I take it. His ideas were even more unworkable than what the Communists tried. For example, he didn't understand specialization and thought people could just change jobs each day based upon whim. This is a big reason why the Marxists have never been able to convince the working class and why their support always came from the bureaucracy and not from people who actually did the work.
I understand it perfectly
I don’t agree with it for more fundamental reasons than you describe
Namely that he was trying to apply Hegelian dialectic with political philosophy when the dialectic is an empirical dead end mathematically so could never even theoretically solve the problems he was pressing on
Don’t confuse understanding with agreement
