I guess, if you think in NFTs all day and truly believe that your JSON receipt is worth anything and gives you legal ownership, stuff like this happens to you in the real world, too.
Fortune, e.g., misinterpretes it in that same way. Anyone can make copies of an NFT backed asset unless you use other legal or technical methods to limit copies.
That definition isn't wrong. However, the "one-of-a-kind digital asset" is the NFT itself—basically a digital autograph—not a copy of the image (or book) the NFT describes, or even a license to such a copy, and certainly not the copyright, unless the copyright holder explicitly agreed to that when minting the NFT. (And you would need some out-of-band proof that the NFT was truly minted by the copyright holder.)
