Read about the economics of market failure and then watch the libertarian debates. It's disappointing how sure they are that the market solves everything. I clicked on a random minute and heard them talk about eminent domain and global warming, two areas where there is clear market failure.
The next-level libertarian response is accepting market failure, but pointing out that there is no reason to believe government can solve it. And I'm on board with that. But listening to libertarians bypass public goods and negative externalities is disheartening.
