Or just straight-up stolen art. For every one artist selling NFTs of their own art, there are easily five NFTs sold by fraudsters misrepresenting themselves to have to right to do so.
I'm starting to wonder if we won't eventually go back to "this NFT certified by Christies of New York" otherwise they are basically all worth 0.000000000000000000000000000000000000000000000000000000001 BTC
If you have the artist's address you can always check that the NFT originated from them. I don't even understand why anyone (mostly non-crypto people) would think it prevents copy pasting.
To be fair, they do actually have some, but all of those can be better served without a blockchain, which as implemented doesn't even help with decentralization, let alone other claimed things.
Well, unless you count market speculation - that's what NFTs currently excel at.
