Yarvin has stated he absolutely is not the person on top. That he’s not cut out to be that person. His role is the philosopher; more a priest than prince.
Those tend to get killed pretty quickly, unless they are completely willing to subjugate themselves to the person on the top.
Either Yarvin is so ignorant of history that he’s barely worth listening to, or he is actively malevolent, and intentionally deceptive, OR he has absolutely no qualms about bending his “philosophy” to the whims of whoever happens to control the executioner.
It’s a great quote and true if Sam Altman is any example. I don’t know Yarvin but he has pretty much explicitly said and taken actions which suggest he’s not interested in ruling. He’s written many thousands of words why he wouldn’t be a good ruler.
Yarvin doesn't want all the bother of trying to become a monarch (a lifetime quest), but I'm sure you can think of historical advisers to royalty that have made themselves indispensable to several generations of rulers.
