Objectivism comes with a bunch of baggage about e.g. economics and psychology that's simply untrue, empirically. For instance an objectivist would say that status seeking inhibits self-actualisation. The objectivist plan is to learn to care less about status. As I understand the evidence, this is bad advice for almost all humans, as almost nobody can self-modify to just not care about their place on the totem pole.

In a nutshell, I think objectivists live in the "should universe", and this leads to a bunch of whacky nonsense.
