You're probably gonna end up being killed or arrested, so you may as well go full on.

I spent like 6 months going over leg entanglements and submissions every Saturday one year as a blue belt in BJJ. When I finally went to a tournament that allowed them I fucked it up so bad you'd have thought I saw it from YouTube and didn't bother practicing first. The pressure of the tournament was too much and I lost to somebody I was frankly more athletic than when I started with the upper hand.

The point being that violence sucks really really bad. It's a lot of pressure and it fucks up your brain bigly permanently. You probably go around dreading the day you planned to do the coup and you have no recourse, you can't tell anyone about it, and it's a big deal that you're doing it. If you're not the government with your monopoly on violence, you're probably in some rinky-dink training facility if you have anything at all, so you don't even have training to fall back on. When you think about how you're probably going to end up being killed or arrested, that's just more adrenaline that makes you do something but probably not something productive. You're liable to start fragging comrades and texting your crush more than you're liable to martyr yourself in order to create an opening that your other terrified comrades have the presence of mind to take advantage of. If you survive the night and the adrenaline fades you'll look around and be like "idk why I texted you, I'm an idiot. Can you post a billion dollar bail for me? I'm in Guantanamo rn."

If you're not doing a military coup then you need so much popular resistance that you win by virtue of Brownian motion letting someone stumble into a winning position because every other position was taken. And in order to do that you'd have to start by letting the people know they have nothing to lose but their chains so that they'll read Marx. I doubt liberal or is going to do it. Fash only works because you already have all the power.
