Nowhere is that ever implied. The idea of militias back then was the same as it is today. The way to secure the existence of a free state has not changed. The military is the government. What you’re saying is like describing the founding revolutionaries as an extension of the red coats. The military does not water the tree of liberty. If anything it’s in the interests of the military and other government mercenaries (police) to prevent the tree of liberty from being watered.
