NFTs are pure, unadulterated insanity.
Only the law stops you from using IP without permission today. And only the law will stop you with what you propose.
It's useful to keep track of ownership of digital goods. And if you did it in a centralized way there are issues with that. We have seen with Amazon and Apple that there can be issues with ownership getting revoked, or services being discontinued as with Google music. It may also not be transferrable. And if you instead make the Government keep track of who owns what there can be some privacy concerns.
NFTs don't change anything, they're not real ownership.
The point is there are no benefits. At best you changed how the paperwork is stored, which is a non-issue.
