As I understand, most NFTs don't confer any copyrights. So unlike a deed, it's not a certificate of ownership of the content at all. Some other entity still owns the content in the legal sense.

Yes, one of the “all kinds of problems” I mentioned upthread (this one isn't an inherent problem with NFTs, but seems to be a practical one with many current NFTs) is that while NFTs certify ownership of something with regard to the linked content, exactly what that is (beyond the certificate that is the NFT itself) is often not clear, even, AFAICT, to the purchasers.
