h/t WRSA: Food For Thought
Somebody's saying the quiet part out loud. (FAIK, has been saying it for some good time, and is only now getting traction). Whatever the reason something like this is turning up, it's a good thing. RTWT.
The American colonies were largely self-governing. Happy to have Daddy's help when the French and Indians came calling in the mid-18th century, they weren't so happy about getting to pay a disproportionate share of the costs. But they already had their own governments, and knew how to run what needed to be run. Colonial legislatures were already in existence, the only thing they had no input on was the persons made royal governor by the King. These offices proved easy to dispense with; the rest was co-opted.
As the author of the OP notes, all successful revolutions, and in fact, our own Unconventional Warfare doctrine, repeatedly points out the need to mirror TPTB with an underground government structure. Which unplugs the tyrannical government from the people, and the people from the tyrannical government, delegitimizing TPTB on the spot.
If you're some large "L" Libertardian, who thinks anarchy is something that has ever worked, you've got another think coming. You won't get the Wild West, either, you'll get the South Side of Chicago in the Roaring 20s, Beirut in the 1980s, and/or Bosnia and Serbia in the 1990s. Nature abhors a vacuum, and if you can't or won't run things, warlords will step up in your stead, and you'll just have traded one dictatorship 1000 miles away, for 1000 dictatorships 1 mile away.
By all means, figure out a minimal government, but you're going to have to have police, fire/EMS, trash collection, water, power, communications, etc., or you and your tribe will be cooking rabbits and living in leather tipis for a long, long time, until some bigger badass tribe rolls over you. Ask the Cherokee and Sioux how that plan works out for the second-place contestant.
A lot of government rent-seekers will be wholly suitable to roll into the new lash-up, and a lot won't. Some, in fact, should be actively barred from any such positions for life, lest you recreate the nanny state with all its drawbacks, and none of the benefits of modern society. For example, your fire and EMS folks are probably able to roll over without a hitch. Your police not quite so much. Your unionized civil servants, diversity awareness officers, and petty bureaucrats not at all.
So you'd better have a plan for that, and them.
Not by tomorrow (though that isn't a bad idea), but the sooner you start working on the shopping list, and deciding on the components of the layers, the easier it is to bake the cake when you need it. Local and county/parish level is good enough for openers. Levels above that will shake out as necessary on the day.
Take a hard look at what your city and county do, and start pondering (and discussing with LMIs) what on that list needs to stay, and what needs to go. Even as a pure thought exercise, it starts getting your head in the game for what will eventually become necessary.
Water, shelter, and food are necessities. But you're not going to make it as Batman In The Boondocks, and if you can't wrap your head around that before you're in the middle of it, you're going to have hard sledding come the moment.
Once you figure out what you need, you can sub-divide it down into what those needs will require in order to work. Ideally, by subverting or siphoning off support for the current PTB, and ultimately by having the various parts of it thoroughly penetrated, infiltrated, and subverted. And the parts that have to go already metaphorically marked with red tape for culling, as appropriate, when the time arises.
Barbarism is easy. Civilization is hard. But the payoff of the latter over the former is tremendous.
