I think the issue is just that NFTs solve a problem that doesn't exist. Any system where an experience is gated by user attestation is necessarily self-contained (asset, payment, user account) to more effectively extract money from participants. No one is federating this, and what would they gain to do so?

There is value in perhaps validation of proof of membership in entities where they have mutual agreements to unlock extra capabilities without having to link their backends, but there are other ways to accomplish the same things... like OAuth.
