In terms of "unified IP registry' I'm not talking about a single centralized organisation, but a super-ecosystem of multiple sub- NFT ecosystems:

- Each do due diligence of creator ownership before an NFT can be sold on their platform.

- In addition, they test the candidate-NFT against the file and perceptual hashes on other trusted peer ecosystems

- Due diligence signatures are portable and transferrable, so ex. Sotheby's validation could be used as evidence when token is resold within OpenSea ecosystem - even if Sotheby's was to hypothetically disappear (assuming old signatures are still trustworthy).

(caveat: Perceptual hashes are starting to push past my technical expertise, not sure to what extent perceptual hashes would be economically feasible: can they be specific enough to not cause excessive false positives while still identifying true positive subtle image manipulations without drastically increasing on-chain storage costs?)

I think the benefits of decentralization would be nice, but it's certainly arguable that an ICANN-like international centralized consortium could be a better solution - it certainly can be more energy and cost efficient but at the expense of that entity being a single point of failure.
