If the only purpose of the NFT is to serve as a digital certificate of authenticity for a “limited edition” file then it still isn’t serving any point that couldn’t be better served using less resource intensive means… like a signed piece of paper.
Plus a limited-edition print is just that—limited. If I could walk into a photography gallery and covertly right-click any print I saw to create an identical print for my own home—accurate down to the individual atom—then the market for limited-edition prints would look pretty different than it does today.
