Yes, agreed. There are a few disagreements I've gathered concerning this--

1. You can't expect people not to maximize. Incentives need to be set up properly to encourage "the right thing". -- My response to this is it's already there, it's just a matter of short term vs long term evaluation (This is pretty vague, admittedly).
2. The notion that self-voting is a base-line, fundamentally 'netural' behavior, and that one can/should do better. -- This isn't comforting to me, because I still consider that neutral behavior to slow down growth. It's like, to borrow something I read somewhere, "wasted inflation". May as well not have inflated the currency at all.
