Of course, this is a nice way of saying that slavery
doesn't make rational sense - that it's a case of pure "might makes right", exactly as common sense would suggest. Think about it - if your slaves are "loyal and hardworking", do you even
need to enslave them by coercion? Of course not - they'll work for you voluntarily as long as you treat them in a way that they accept as fair! (And oftentimes - perhaps even
most of the time - they turn out to be a lot brighter than you gave them credit for while treating them as mere slaves.) And if this is the
best case, what about everyone else? No, what the slaveowner really dreams of is that he's going to control his slaves purely by their
fear. And Moldbug is saying: "nah, that's not going to work. Deal with it."
Way to miss the actual argument he's making, dude. You were not even on the same wavelength.
