And yet, NFTs grant no 'rights to use': licensing, copyright, terms of use, or any other legal terms of the sort. At its heart, it's because blockchains are not widely recognized as legally authoritative. They /cannot be/, since there is no guarantee that an image is uniquely identified by one NFT across all blockchains, and therefore a court would be required to pick and choose 'winners' when considering which blockchain rightly determines ownership.
