He could just as conceivably be a thoroughgoing bastard, with no form of redress for the people.
Imagine 10-20 years of Obama.

No doubt the best and most stable form of government is a benevolent monarchy.
The problem is, until Shilo come, there is no such thing.
He could be. Many kings were. But note that (1) a king is brought up as one, which mitigates the risk; (2) he can yield to a more capable and service oriented relative, or even a regency, without jeopardizing his own status; (3) the last thing an asshole king ("bastard" in reference to a king is a double-entendre) would want is to annoy his subjects. Typically, kings without civic merits simply enjoyed their private lives and did not cause much trouble.
In contrast, a democratic system programs the politicians to be of low character: he cannot admit when his opponent is correct because then he should lose his office; he does not have a luxury of a long term view; he is a salesman and government is his product. No wonder we have deficits as far as the eye can see.
