I don't think that's true at all. If you go back and read his stuff, it ages pretty well in my estimation, largely because _why was apolitical. And he was way more informed by good humanities sources than any average Portland woke hipster.
I mean, he is pretty expressly anticapitalist in this work. The name "why the lucky stiff" is found in Rand. _why was regularly political, though it wasn't always a focus of his.
