Right. You don't need a license to protect your legal rights. You haven't asked all your friends to sign licenses promising not to rob you because theft is illegal. Record companies shouldn't ask people to sign agreements that they won't break the law. The law is already written. Why do you need a license on top of it? Licenses are for covering situations not covered by law or, more notably, for giving away permissions which would otherwise be covered by law. If you were going to allow one of your friends unrestricted access to your car, it would be a really good idea to give him a signed license agreement so he didn't get arrested for stealing it. If you don't want to allow your friends unrestricted access to your car, you don't have to do anything.
