it still doesn't solve anything. You have no way of knowing if the pixels were originally signed by the real artist or not.

The only reason it works right now is because that NFTs are so recent that you can just send a DM to artist's twitter to verify if the original set of crypto keys/wallet belong to them. When the artist himself is promoting it, it's not hard to figure out if it's genuine or not. But what happens in 10 years or if you can't trace the original artist?

How would you know if I took the picture myself or if I stole it from flicker? if reverse image search doesn't work, it would be impossible.
