From what I've seen of AS, she believes that the creation of value is good, and that trying to create a system where effort isn't rewarded will lead to people not putting in effort.

There's also all the discussion of sex in AS, which, assuming it's actually relevant to the story, leads me to believe that Rand thought of emotional and physical pleasure as being two sides of the same coin--that is, there's no shame in either. However, sometimes sex is just sex, to paraphrase Freud.
