I guess if there is an issue with verifying authenticity of art and using NFTs solves that issue this makes sense. Selling digital art using NFTs is still dumb IMO, as there is no real concept of owning or displaying an “original digital painting” like you can do with normal paintings; in that case you only get a fairly abstract proof of ownership (NFT avatars on various sites and NFT items in games could change this if implemented widely I guess).

Other than a few similar use cases they still don’t seem very useful, and it I think in most cases they solve issues that already have good solutions.
