Yeah, but you'd accomplish nothing. Because the only way a registry could be meaningful in determining ownership, is if the government that protects your property rights considers the registration valid. And in that case, you have to trust the government which means a trust-based registry is far more simple and efficient. Could still be blockchain based though, with proof-of-authority. Could be nice to see a ledger seeing exactly who signed (with cryptographic signatures) the transfer of the property etc. Okay, that' be a kind of NFT-system, but not in the sense that most people think of NFTs (trustless)

For houses this is easy to prove. But this goes for nearly every other suggested NFT application, including tickets.
