Oh yeah I just latched onto a portion of your comment that was suitable for my soapboxing, I didn't mean to sound adversarial.

But more generally I don't think there's a good technical solution to this problem. You'll never "own" Iron Man, Star Wars or The Godfather in a true sense, only a license which gives you some rights. Even when you bought physical media you weren't allowed to do many things, such as public viewings for instance. Not because of a technical issue, but a legal one.
