That's actually the point. Fire and police and roads are all very, very cheap compared to wars, nation building, etc.
People are tired of paying for things that they don't agree with. I can't say that I blame them too much.
What do you see nation-building as, if things like roads aren't part of it?
Wait, what? No charities exist that create these organizations? Oh darn, hoist on the reality petard, whatever will we do? Pay taxes you say?! But no, let's just have smaller government! Nevermind that we will have children with lead poisoning, plant workers with cancers, or zero safety net for the elderly, working poor, or disabled. At least I won't be paying taxes!
