NFTs are a receipt. There are some areas where having a receipt/proof of purchase in hand is useful (ticketing/licensing), but that utility is separate from the thing you are proving to have purchased.

NFTs can be interesting if you're interested in novel licensing schemes or safe secondary markets for concert tickets, but it's definitely niche. The "interest in NFTs" beyond that is just everyone's natural inclination to try to make a buck before the music stops.
