There's $1T+ of cryptocurrency held doing mostly nothing, and investors rightly want to put it to work. That is what spawned NFTs, crypto art, DeFi, and basically revitalized the crypto economy.
NFTs specifically are interesting: it's a new class of asset that allows digital work be allocated significant crypto capital essentially out of thin air, where it otherwise would have none.
As an artist, entrepreneur, or entertainer, you have a new way to make money that is not paid for by users or advertisers, which is the way it usually goes. Instead it is paid for by crypto investors and newly minted millionaires who have capital to allocate and will allocate it to your work.
Combine this with social signaling, FOMO, and a general lack of regulation and the result is innovation.
Seeing NFTs through the lens of DRM is completely missing the point.
