Reading about FOSS philosophy, degoogling, becoming against corporations, and now a full-blown woke communist (like Linus Torvalds)
You’re right. Communism is like the greatest social form a society can possibly achieve. The Problem is, that humans are dumb and will always try to get the best out of it for themselves so the concept of communism is ruined by those people. It maybe is practicable in small “society’s” (your family as example) but fails in big societies like states.
Yes, Communism fails to acknowledge human psychology and will therefore never work. People are individuals with self interests. This can never be controlled (without violence) by a socialist/communist society. The good news is you only need selfishness in a free market society. In order for people to get their needs met they need to offer value. Value exchange means all people are better off (on average).
