Mencius' conception of useful hierarchical authority models puts CEO and Monarch in a similar space.

In the sense that there is a single guy at the top, I suppose. But then by that logic you can argue Moldbug ought to have no problems with a parlamentary democracy with a prime minister. The point is not that there is a single guy in charge at the top, but the system of incentives that girds the society and gives it shape. There is a big difference between the British monarchy in the Stuart period ("bring back the Stuarts!"), and what Moldbug is actually advocating.
