The family of "Charlie Bit My Finger" sold that video through an NFT. So I wonder if the family would still use that video, and the NFT owner would sue them... who would win. I would actually think the NFT owner.
My point was, if the media rights could really be tied to the NFT rather than the auction contract then you would have something of value, but right now it would just be "Here is an action for media rights. Oh and btw here is also an unrelated hash you get with the purchase". As is for the media rights to go with the NFT you'd need to write a similar contract for every trade. At which point the NFT is totally superfluous, why not just write normal contracts skipping the NFT?
