I am ALL IN on your view of the future. Where do I send my money? :-) It is truly what I hope for, but... ... Trump is Osama Bin Laden. He has put forth a belief/philosophy, and empowered anyone to claim fealty to that belief, and act in his name without his permission. The white supremacists, Michigan Militias, and Proud Boys are Al Qaida cells. They operate autonomously, funded by the same dark money sources, and sometimes coordinate their efforts through whisper networks. The loss of Trump/Bin Laden doesn't disempower the people who still believe in their White Supremacy mission... it emboldens them. They now need to redeem their god, and show he (and they) were right all along, and push to establish their Caliphate on a new piece of land. (How much you wanna bet they don't set up their training and indoctrination camps on the coasts, but instead go to the wilds of middle America?) If you've been rolling coal on your neighbors and flying the Trump flag from the back of your BroDozer for the last 4 years, you don't quietly go away. You go bigger. And that's gonna be a real mess.
Just don't put it in the stock market. :) I think you give these groups far too much credit as combatants. Al-Qaeda fought a difficult war against the Soviet Union and Afghanistan before Bin Laden turned them against the West, and they were backed and armed by foreign governments (the US playing a prominent role). Those supremistst and militias are somewhat disenfranchised domestic working class folk. They have mortgages, truck payments, and enjoy deer season. Also, Biden doesn't scare them as much as Trump wishes he would. That's why Biden scared Trump so much.
Oh, I don't think Y'all Qaida will be effective fighters, but their skill is always choosing to pick on the weak and disenfranchised anyway. They don't stay around and fight, because they always lose when it comes to bare knuckles. I do think they will roam the streets, menace people, and demonstrate the "utter lawlessness in America that Joe Biden is letting happen to good, working class people", and make Joe The Plumber wish for an authoritarian to "Take Control Again like Trump did!"
