And it was an agreement, and no it was not unjust. Yes, it is a monopoly, and no it doesn't rest on force, but does that matter?It does rest on force. People who refuse to accept the imposed rules can go to jail. And that does matter to me.
You don't have to have every song or movie that's ever been made. You are not entitled to them unless you strike an agreement with the owner of the property.
Of course not. If I thought that I'd be suing or somehow forcing the copyright holders to give me copies of their work. I'm not entitled to anything, I'm merely accepting what is being shared with me. It's the other copyright (and patent) holders who think they are entitled to have special protections paid for by the rest of society.
By the way, they might call it property, but that concept only makes sense as a system for dealing with scarce, rivalrous goods. In this case, it's nothing but a marketing term.
