Not sure why, assuming all the rest of your theory it valid, you remain so certain the US will break up soon (as opposed to say, in 100 years). The civil war prevented the last break up. And just as our political systems are too rigid to evolve to meet the moment, so too the inability of the system to allow for reformation of different political entities may yet help to keep it together - unlike the “United” kingdom which allows for independence referenda. Even Quebec could legally separate, if its citizens voted for it. But there’s no way to do that in the US. Love might not keep us together - but the real fear of chaos might.
