The government just takes more from me, or makes some more with that handy, unconstitutional Federal Reserve. Let me answer that question with another. I know that I'm a perfectly healthy, able-minded adult, and so have an advantage over many others in this country, but please remember that we are not guaranteed life, liberty, and happiness. We are instead guaranteed life, liberty, and the pursuit of happiness. Taking my money and giving it to a bum doesn't really make either one of us happy.
Defense is obvious, and provided for explicitly in the Constitution.
I've driven on the Kansas Turnpike. I am making assumptions here, namely that the combination of tolls and whatever the gas stations and fast food restaurants pay for the right to set up shop cover the price of the beautiful road. Technology now exists so that drivers would not even have to slow down to pay the toll to drive on such beautiful roads. I would gladly pay a toll to drive on freeways in exchange for that portion of my taxes. If you don't want to pay the toll, fly or walk.
