I was being sarcastic; there is no legal basis for an NFT to be any different than, say, the URL in your browser. You can copy it all you want, but it doesn't convey ownership in any way.
The application is B2B trading of assets between dealers, so they don't have to mess around with devaulting every time the assets change ownership, introducing risk of fraud every time.
There is also a lot of insurance involved, to answer your probably next question: if the vault loses something or an employee accidentally drives a forklift over it, the NFT holder gets paid.
It works. Pilots right now, but it works.
