Every like to an AI-generated work is (literally!) one more data point in support of record labels dropping human artists for AI artists that will do what they want, perform where they want, and give all of their profits back to the label.

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.

Perhaps knowing a human with talent worked on it, putting some small part of themselves and their lived experience into the music has value to them? If so, then their actions make complete sense.

It's not asinine at all. Context matters in art. Otherwise, more songs exist that I would probably really like than I will ever hear, so I'm going to focus on the human-made ones. Besides, part of the joy of music extends beyond listening. For many people, myself included, if we feel really connected to a song we like to learn about the people who created it.
