Did you read the rest of his series? He addresses this in part 3:

> You’ve probably noticed this theory is hard to falsify: You think you’re not playing taste games? You think you “actually like” things because of the properties of those things? That’s because you’re playing higher-level games! And it’s rather convenient that this is all supposed to be unconscious. There’s also this weird sense of guilt. If you consciously change your tastes so you can fit in, that’s bad. If you unconsciously do that, that’s worse. If you unconsciously don’t try to fit in, you’re scum.

Meaning what? That true enlightenment is to affirm openly all your likes and dislikes with no care for what anyone else thinks of them?

That's what Virgina Woolf said.

To be highbrow, you can like whatever you like as long as other people don't like it too.

(She didn't say that last part out loud, but it's strongly implied.)
