This is not true. For example, ownership of an NFT (and burning it) can constitute payment for an intellectual property license to do something like put music into an advert or use it in a film.
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.
