How about we disband the federal govt, let the states be sovereign and purchases any services they want from any source they want instead of being forced to purchase from the current federal govt?
Just a thought ...
That might work right up until the point that the states need 1) protection from foreign invasion, 2) a common currency with which to conduct interstate and international commerce, and 3) being able to project common interests to foreign powers (would each state be required to purchase and maintain their own embassies in foreign capitals?).
Besides that, it is not a bad idea.
