Well, that’s the point. In order for that system to work as described, you would need some kind of centralized authority to validate and enforce it. Once you’ve introduced that piece, there’s no point using NFTs anymore - you can just use any kind of simpler and more efficient key/authentication mechanism.

So even if the corporations wanted to use such a system (which, to your point, they do not), it still wouldn’t make sense to use NFTs for it.
