Regarding your particular questions, in May 2003, 79% of Americans thought the Iraq war was justified, so the majority clearly didn't oppose it. Most now believe it was a mistake. Only 41% of citizens agree with the president's plan to close Guantanamo. A majority of Americans think the TSA is doing a good job. I think the majority of Americans are wrong on all of these things, but they are undeniably popular opinions.
I, personally, am not being robbed. I am also not being tricked into obedience. Your insistence to the contrary, entirely ignorant of my actual situation, is arrogant foolishness. I've lived on four continents, and I'm quite happy with what I have here.
Could it be better? Sure. Is it at risk from powerful interests? Definitely, especially at the federal level. But I also see many causes for hope.
But if people want to enjoy the benefits of living in a city, state, and country, to participate in an economy, those benefits come with obligations. Sure, they may not want to pay for things. But if they can't get others to agree that the government should not do those things, or at least should run them on a cost-recovery basis, then it's too bad.
They certainly have the freedom to move to someplace without effective government. E.g., Waziristan or Somalia. They will be much freer there. Of course, warlords will be free to rob or kill them, so it may not be entirely to their tastes, but then, we aren't guaranteed perfect choices, just the opportunity to make better ones.
