Just spitballing here. Maybe some kind of legal framework. Some legislation that controls who is allowed to create NFTs for a work. Something that judges and courts can use to enforce the right to sell an NFT. Something that bans anyone but the original creator from distribution of the work the NFT is for. Because a "fake" NFT is any NFT that doesn't control the work it is attached to, right? But NFTs are just a thing on a block chain, so we need a contract to link the NFT to the work. And we will need the same contract to be enforced by the courts.

So, we need a contract to link an NFT to a work. That contract should also spell out all the things the NFT holder can do (maybe the creator didn't want to, or isn't allowed to, sell all rights).

So contract the says who owns a work and what they can do with it, enforced by a legal framework and the courts. That us all you need to make NFTs make sense, I don't see what the problem is.

What's that? If you have the contract, why do you need an NFT? Well, what scrub would buy a paper contract with bitcoin? It's not even on a block chain!
