"using the state for 'our' purposes makes the state stronger. "
I mostly agree with this, but... but - well there's something naggin' at the back of me skull to tell me this is too simple to hold alone.
If we use the state as it intends itself to be 'used'/interacted_with (for example, calling the cops to rat out the naughty fascistas), then it definitely (in our minds) reinforces its strength and accentuates our weakness.
If, to the contrary, we were clever enough to find a way to pit against each other the multitude of factions that comprise the 'monolithic' State, let the state's gears grind against themselves for a change. For example, spot of a couple of city cops hanging with the fascistas (there's always a couple), then blackmail the mayor's office to deal with them - 'a copy of this file will be sent to every media outlet in three days, etc'. So, the cops are pissed at their brass and the mayor, the brass are pissed at being pushed by the mayor's office and at the dumb cops for embarassing them, and the fascists are pissed at everybody. It never really works like this in real life; but i think the idea has some merit - if there's a dozen thugs fighting to get through a single door to beat the shit out of me, then i should be able to instigate at least a single squabble amongst them and get the hell outta the road.
