I generally am not fond of NFTs myself, but want to give a counter point - while it's no fun to see artists you like posting a lot about NFTs, it's also great they can now get paid to do art. For established artists this means high purchase prices that (in the thousands, not something crazy) that make being a full time artist viable and acts as pay off for doing it for many years without much of a financial incentive…
I somehow doubt that NFTs provide a sustainable way of increasing the amount of money spent on art. If an artist couldn't make it by selling prints or collecting donations in the past, why would people now suddenly spent more money on that artist's art just because instead of a print you get an NFT?
PS I'm not exactly rich as a grad student, so I've just spent about $100 so far. No idea if any of what I bought can be re sold, maybe I'll look sometime.
