> Next time you're doing production work on a TV show or movie and want to use a piece of media in your production without licensing it, try running "Hey, we can just right-click it" past the studio legal department. I'm fairly sure they'll have some objections.

Yep the only thing that stops me is centralised copyright regime, not Blockchain. Blockchain can be a proof of license/ownership but not because of its inherent value, but because we believe particular issuer. Also it's fairly easy for Blockchain to loose connection between who legally own/license particular art with what is on it. Copyright is hard, and sometimes the answer is we don't know.
