That’s the point, a use case where no one has to. It’s only the record of ownership.

And clearly you’d still need to make arrangements to prevent multiple chains of ownership for a copied artifact

NFTs make the mistake of assuming that somehow makes it unique, forgetting you can just copy the original. However these use cases work from the opposite direction: given an accused infringement, does that match?

Consider the current use case for trademark. Someone creates a trademark and registers with an authority. At some point they may renew modify, or sell. After some time, that authority has a database containing the original and a chain of ownership. Blockchain could serve this identically, with the potential advantage of the chain being self contained and distributable
