To be blunt, COMMUNISM IS NOT A CLASSLESS STATELESS MONEYLESS SOCIETY.
It is the real movement to sublate the current state of things.
Yes, class antagonisms will resolve, the state as we know it, will wither away, money too, will, but these are not simply what communism is.
Communism isn’t a goal, or an ideal. That’s why Marx called it a movement. Communism continues even after the state withers away. Have you thought of that?
Communism is the unimpeded movement towards sublation of contradictions in history, not a stage of history.
