The KillDozer is an appropriate example. I cheered for that guy, along with many others. Some of the corrupt town officials got their comeuppance. But what did it really accomplish systematically?
The issue is that those toys have workarounds, especially for locals. The soviets ran into these problems several times. Sending tanks piloted by locals to put down locals often ended in a stalemate or worse (The locals cant tell whose piloting the tank, the tankers can identify their neighbors however)
If you want to narrow things down to guns keeping local politics straight, there was that recent business with the hardware store shotgun vs Shinzo Abe. The shotgun gentleman seems to have gotten every single demand met.
But that is not the point I'm making. Like sure, I agree that a militia wielding small arms can resist an invading army, say in the case that the US military was defeated or didn't respond to an area because it wasn't considered strategic enough.
The point I am making is that it's fallacious to think that weapons can do anything to push back against homegrown democratically approved bureaucratic tyranny. As I said in another comment - how can a gun, explosives, or even a tank alleviate the problems you will face from not getting a building permit?
If there aren't enough people for that, then it's not actually a secession but rather just a few rebellious people the bureaucracy will eventually grind down. And the hyper-individualist suitcase nuke idea from Snow Crash is quite compelling, but so far seemingly untenable.
And neither one does anything about the extra-governmental system of control when you go to sell your house and the bank cartel sets the price much lower due to all the "unpermitted" work.
As far as resisting "government" in a democracy, it is much more likely that one side of an ideological divide wants to subdue the other (or both want to subdue each other using force). More like Republicans vs. Democrats and not really the people vs. the US military. One person's terrorist is another's freedom fighter.
