It's important to realize that that's not actually true. I think we should have a small government that protects citizens from force and violence. That still includes all the core functions of government (e.g. police, courts, military, I don't care if you throw in basics like roads).
That is a world apart from Somalia, or anarchism. It's actually just a return to earlier ideas of American government that served us well at the time.
To be clear, I'm not a libertarian, for reasons that aren't relevant here.
