> Good governance takes intelligence.

True, but that doesn't mean intelligence is the bottleneck of good governance. Good governance also requires simple, plain brute force. You have to herd millions of cats, all of which have their own intelligence, and the richest of which are basically giant tigers. At our current level of individual intelligence, we have plenty of simple solutions to many of the problems that plague us, but the reality of the boiling ocean of society is that it tends to crush them faster than they can be built up.

When the problem is the coordination of intelligent agents with disparate interests, increasing everyone's intelligence isn't necessarily going to lead to a solution. Maybe if everyone operates in good faith with a compromising spirit. But if our best solution creates losers, they will fight to the bitter end, in which case we don't need intelligence as much as we need a bigger boot. That's governance.
