The fantasy of standing up to The Gubment comes from two things:
1) a rambo fantasy. a serious overestimate of your own skills where now YOU are the one in charge
2) a supposition that "if it ever came to that" the military and the police wouldn't actually pull the trigger.
We know this is nonsense from historical analysis. From the other side you can look at how the Vietnamese people defended themselves from invasion and if you really think those conditions exist here then you've never been to, say, arizona where this sort of thinking is prevalent.
Edit: I wanna be clear that i don't think this is a good thing. I wish there was some way citizenry could hold their government to account directly like in the 1700s but I think we live in a different world now. One where people enjoy not having a random street war kick off on a tuesday when they'd rather be at a coffee shop.
