I'll argue a bit more with you offline after I review the Federalist Papers, as you suggested, but to me you are the one exhibiting a fundamental misunderstanding. The authors of the Federalist Papers, and of the Constitution, had *zero* interest in protecting the interests of "the citizenry", 91% of whom were farmers when the Constitution was adopted. An armed militia was needed to protect the rights of the powerful *in each state* against the federal government. There was no interest in balancing power of the state against the population, only in the states (i.e., the powerful elites who controlled them) versus the federal government. As John Jay, one of the hallowed Founding Fathers, remarked, "Those who own the country ought to govern it".
And to argue that 60 million individual citizens, widely dispersed, with no independent means of communication, could somehow be a "threat" to our government is outlandish. The federal government has acted violently whenever it likes, and is only deterred when it might be caught on television, not when an armed group of citizens opposes it.
