The problem (as others have said) is ownership is a legal construct not a mathematical one. A smart contract may not be recognized as a valid contract in a court of law, or have precedent over say the actual handshake agreement. Even ignoring that, many NFTs do not convey any ownership of the digital work, but rather of the NFT itself. So far the most likely value is in a platform that actually lets you leverage that ownership, such as Meta letting you put a framed monkey on the wall in your virtual home. But that sort of platform tie-in means it is basically the same as say the DRM-encoumbered media stores we've seen go bye - ownership which is only recognized within a platform is only really providing durable value to that platform.
