That’s the whole point of communism is for everyone to be equal, and for everyone to own everything and not own anything at the same time. That’s the entire foundation.
Our mutual value is for us the value of our mutual objects. Hence for us man himself is mutually of no value.
Communism assumes all men are equal, and all labor is equal. All things belong to everyone and no one.
This doesn’t work in reality, people want to get more than others if they work harder.
