NFTs are not a copy of the art. On a technical level, they're hashes of the item for which you're paying to store on the blockchain. You can't get the original work from a hash, only verify the accuracy if you already have both. Then on a legal level, you do not give you any legal right to even view the art. The artist isn't signing you a license to copy the work, and, as described, a hash is not a copy for which such a license could be implied. If you buy just an NFT and send the US registered artwork itself along with it to the buyer, that's copyright infringement, and the original artist could sue you for thousands of dollars.
