This is exactly why having anything approaching a ruling class is a large hazard to avoid. Intermediate steps between citizens voting and power being executed are an attack area for people with selfish interests to inject themselves.
And moreover, we can't trust each other fully. We can try to aspire to it, but none of us can honestly say we just want what's best for everyone.
Just because someone is smarter than you by some measure, doesn't mean you're better off letting them rule you.
