How can one expect rule of law in tact and spirit, when everybody engaged in the exercise is an idiot?
Your error is the claim that everybody engaged in it is stupid. That obviously is not the case. Certainly there are plenty of lawmakers, judges, lobbyists, etc who are stupid, but most are pretty smart. They tend to think through the ramifications of laws--that's not to say that it's always perfect and not stupid, but democracies have been able to thrive and be highly productive in spite of the occasional stupid law, lawmaker, or law lobbyist.
That was a very long way of saying that democracy sucks.
No, it was a short-ish way of saying democracy is imperfect yet pretty damn good...and vulnerable.
