Ownership is one way to interpret the meaning of an NFT, but that's not the only way to do it. For instance, you could use them to keep track of responsibility/permissions: "The holder of this token is the project maintainer, only they can approve pull requests". That sort of thing. Interpretation is up to the users, I'm really just talking about nonfungibility in general here.
