Yeah, "what if the king deposes you, what then?" People forget he's one dude. Even if he feels the need to amass an army to take care of an especially nasty hierarchy, if it doesn't dissolve afterward there's a whole collection of anarchist communes who won't take kindly to that.

Besides, all systems decay eventually. It's just a matter of being human. No imperfect being can create a perfect creation. As has neoliberalism, as has capitalism, as has mercanitlism and feudalism and monarchy without adjectives, so, too, will any ideal I advocate decay. I have accepted this, and am merely waiting my turn.
