I'd argue that: 1) what is extreme changes over time, 2) a system of government being extreme de facto means it will have less support; the more support it has, the less extreme it is by definition, 3) the less support a system of government hass, the more force will be required to maintain it.
I am also under a system of government that is oppressive and monopolizes violence, but if the government had less popular support, I fully believe it would proportionally ramp up the oppression and violence. In fact, I'd argue that it's currently happening in the US.
