That's not actually true, though. In some sense all governments are posessed of "weapons" like this, the cost of use being only the violation of some norm. Or even law. The "rule of law" is a gentelemen's agreement at its core. Yet the world is filled with basically good governments who broadly follow that code!

So the way you treat that is by calling out and resisting the attempts to weaponize the government in new ways, not just throwing up your hands because it was "eventually" going to be used anyway. No, it's bad. You should say that it's bad and take action to oppose it.
