Taxes are not products or services. They are not the government mandating us to give money to a corporation to purchase a product or a services.
No? If you don't want to pay for Blackwater's contract or a new bridge in Alaska or some piece of pork, and you don't pay taxes because you shouldn't be forced to buy Blackwater's services or that bridge, what happens?
The Fed doesn't have money. It makes you buy what it wants by making you pay taxes to pay for it. Not to mention the whole 'you are the government' concept.
The Cronyism and Moral Hazard of the government forcing individuals to funnel their private resources to select companies is far beyond collecting taxes for the proper functions of government (i.e., national defense, the court system - the things necessary to ensure our Constitutionally protected rights).
Like no-bid contracts and thousand-dollar toilet seats that you either pay for or get go to prison for not paying your taxes?
The only difference is the procedure.
