This is a values question. Many would say that literature has a role in modeling certain behaviors and teaching lessons that are functional in society. Basically the fables and proverbs idea. Simply catering to what feels nice and what reinforces the biases and wishes of readers is not the same thing. Yes, most of literature is already crap and simply caters to readers instead of challenging them. But if you RLHF your way to AI literature that people "engage with" the most, you will get unvirtuous literature that doesn't do this function. Of course you're welcome to disagree with this entire framing and purely see reading as hedonistic pleasure and nothing else.
