No, NFTs are absolutely a stupid idea. Putting a few bytes of data on the block chain does not add any value whatsoever to whatever art is involved, nor does it prove any sort of ownership or legitimacy.

Whether the artist only sells one copy of their art or not, making an NFT is about the worst possible way to facilitate single ownership. This is because there's no practical way to store the entire artwork on the block chain. The images associated with NFTs "live on the block chain" in the same way that the a website "lives in" the URL that points to it - not at all.
