The problem is that anyone can mint an NFT. Verifying that an NFT is actually minted by the artist would likely require some sort of external certification that you can trust. This is done for paintings and other collectibles as well.

What I don’t understand is: Once you have an external certifying authority, why have blockchain based NFTs at all? Couldn’t you save a lot of energy and complexity by tracking purchases in a database?
