I'll admit that the gun thing is a bit of hyperbole.
It specifically refers to my belief that any government action is inherent backed by the threat of force. I can choose not to buy cheerios, but I can't choose to not pay taxes on roads I don't use. (or more topical, I can choose FedEx or UPS, but not which letter carrier I use). It's a bit of an overstatement, but it's still true. Anytime a law is passed, I can choose to follow it, or I can choose to let the government arrest me for not.
I'm not even against government intervention in the interest of regulation and stabilization, it's just that the examples we're talking about here are back-end. By back-end I mean they help companies or people who have screwed up at the cost of those who haven't. The technical term is
Moral Hazard. I have issues with wellfare not because I don't believe in a bare minimum standard of living, but because it creates a situation where people are disinclined to get off of it. As in they are better on wellfare than getting a job at McDonald's. (This is my perception of the situation, feel free to counter).
I'm not sure what the government could do to help banks without bailing out the failures at the cost of everybody else, but a solution that rewards failure at the expense of success is unacceptable to me. I feel even more strongly with the car situation, because I feel that my greatest power in this society is my ability to
vote with my feet. In my mind, nationalization will isolate the banks from the effects of their mistakes.
(If you want the high-techy geek talk-> Market Forces find local maxima perfectly. The role of government is to smooth out the bumps so that the local maxima is ideal, not to force the market into position after it's found an equilibrium.)
