What’s the difference between a capitalist and communist disagreeing about the basis and scope of property (that’s what it really is) and two ancaps disagreeing about copyright?
They’re somewhat similar, but ancaps have more respect for the idea of personal property than communists do. I’d say a difference in opinion over copyrights is very small, since it’s in how to define property rather than trying to rid the world of personal property altogether.
