Maybe if you buy an NFT of an image you own 1/2000th of the rights and then can sue people for 1/2000th of the royalties when they tweet or blog it?

I could get behind that.

One interesting dilemma for prestigious artists is as their work resells at auction at higher prices they don't get any of the money, except when they go create a new artwork for their higher priced market. A way to fix this could be by the artist always being able to make genesis blocks for past artwork NFTs.

NFTs with image rights would be great for news photographers and paparazzi for starters. Or rather it would be good for lawyers representing them?
