The world first becomes civilized when groups and bodies of people have tensioned, proportional leverage against one another - lest there's low incentive for the naturally more leveraging group to engage in virtuous action. Of course, we see it time and time again where both governments AND people use the leverages vested upon them in functionally incorrect or anti-social ways, but it is the closest to an equilibrium between two perpetually-unwieldy groups (governments, the governed)

In a nutshell, the tension of existential leverage that the government has on you through their monopoly on violence is thereby "equally" leveraged by your right to own firearms - and the implicit extralegal right to use it against them - in an unjust event. And a government SHOULD be perpetually worried for when you'd eventually consider something "unjust" enough for you to exercise that right - as it creates a chilling effect for them to even attempt it.
