The most useful NFT I've seen so far is Decentraland's LAND token, which behaves much like a deed to a plot of virtual land. Its something you could theoretically download free gratis, but as LAND is linked to a finite space in a living virtual world, you'll never own it in its entirety by just screenshoting it because your copy is desyncronised from the original.
A photograph, or even a 3D scan of the Eiffel tower does not mean you own it or infringe on the owner's or designer's perceived rights, and likewise a copy of the land isolated from the Decentraland grid does not mean you own the LAND.
Tl;dr, I think NFTs need to focus on being a record or something - anything! Rather than being the new way to buy art, sell the technology as the new way to do deeds, licences, certificates, etc.
