If the power of the government lies in the willingness of the people to be governed, what can be said about the draft? For that matter, what about any law?
Is consenting to be governed worth as much as consenting by free will?
Of course, you have free will. But do you have freedom if the consequences are so undesirable they are almost always a deterrent?
Free will is an illusion, correct? Are our actions not determined by biological reactions, urges, and programming? So it seems "free will" is merely a euphemism for possibility. But then, can anything be done about the state of the cat in the box?
By this line of reasoning, the most potent government is one without laws. Perhaps not the most stable or the safest, but the most powerful.
Then the question becomes one of the primal inclinations of humanity, from that, society.
