The NFT is the property. Social consensus is why people want to own it. The blockchain enables the creation of an ownable digital record. Our legal system continue to function and will still arrest you if you steal an NFT.
Most people don’t understands existing IP laws (see what results you get when searching YouTube for “no copyright intended”); adding a new one isn’t likely to improve the situation, so I don’t accept that there is (nor that there is likely to be) a real social consensus in favour of NFTs.
