The problem is that content providers often want the best of both worlds. I bet if your disk becomes corrupted or unreadable, they will make you pay for another one. If they want to claim they are licensing it, they should be required to allow you to receive a working copy if yours becomes corrupted. This is rarely the case. Either it should be a license or it should be a sale, and it should only be tied to physical media if it is a sale. Try getting a free replacement download of a game or song if it becomes corrupted. So, content providers want to prevent you from selling content by saying it's licensed, but they won't replace the copy if it becomes corrupted.
