I mean a NFT that represents a real world asset is sorta more interesting......
Is it now?
Here is my NFT for sale for a 1000g gold bar. I'll even sell it to for 20% off of spot price....

I think your missing the point. Nft as a public register for land/property etc can be very useful
I think the one way this is useful and secure is on a Bitcoin rooted semi-trusted sidechain. It's a disaster on any fat layer 1 like ETH et al. But I could see a set of government entities banding together using a fedarated sidechain to do land/title registration. THAT is where this goes I think. We do not need full Bitcoin level security, but we dont want to build this on a decentralized blockchain either.
Liquid would be perfect for this. It could even be run by governments.
