I can see you know more than the rest of us. I do like the ideas though. If abolishing the Fed is good enough for Ron/Rand Paul it’s good enough for me.
Disengage. Doesn’t have to be 100% but it should be enough to scare everyone.
Default. A bitter pill yes. The youngest baby boomer will be 100 y/o in 2064. We could fix it by the time he/she turns 80 in ‘44. Baby boomers could make their mark like the Greatest generation who spoiled us. The left will try to trip us up every step of the way.
You are right it’s undoable. Still this will be a crisis and like the left we should not let it go to waste.
Similarly with foreign policy, even my European relatives are embarrassed every time some problem comes up and their politicians ask why the Americans aren't doing something. Many here seem to think we should just pack up and leave, but I think that's even more expensive and definitely more risky. What we should do is offer a deal: meet your NATO obligations or we will bill you for the extra capability we provide, and if you don't pay, we'll tariff the crap out of your imports.
Any wars we engage in should be carefully chosen, brief, and annihilating for our adversaries. Even during our brief dalliance with imperialism in the 19th century, Americans were very leery of liberal imperialism.
We used to be better at playing this game, but our elites are delusional and corrupt.
