Deals with the Devil
I’m assuming this wasn’t intended as a Satanic argument for Monarchy, but it works as one:
Q: Why does the devil keep his deals?
A: As an immortal, he has an infinite time horizon of other deals he jeopardizes if he betrays any given deal. Therefore the opportunity cost of any betrayal is too high.
Q: What does that make politicians, then?
A: Lower in ethical reliability than the devil.
Even a demonic permanent government makes a better contractual partner than the most angelic temporary regime.
