Movie studios are "signing" AI artists from AI studios for massive dollars; this is happening.
Maybe you don't care, but music is beautiful and difficult, and I really enjoy hearing works from people that have a passion for it.
You don't have to worry, though; most people are in your school of thought. "Who cares? It's good." Short-term thinking is best-term thinking.
I wouldn't say it's asinine though. People reject creative output out of personal protest against the creator. Someone might love a movie only to refuse to ever watch it again because they found out the director was accused of something horrible.
Some people just don't want to support anything to do with AI. Although in this case the OP admits to also using AI directly so there's some inconsistency there, which is consistent with the state of confusion and uncertainty OP is expressing.
