This certainly is a problem. The communists believe private property is theft, and then we get into another debate about what property is.
The communist would believe if I build a fishing pole, then that fishing pole is the public property for everyone. The problem is, the only way to force me to give up my fishing pole is to use violence against my body. This is fine if my body also belongs to everyone else, because I have no right to my own body.
To explain why my body belongs to myself would actually be too much for a nostr note π but i definitely recommend you read the book or listen to it on YouTube
