Or rather the answer just as easily could be "Tied up in a closet while my security detail decided to beat my ass and take all of my shit. Since money is now worthless and I have nothing to pay them with"
Money is, by design, worthless. Especially since America got taken off the gold standard & money printer go brrrrr. It's all held up by our faith in the dollar, and the system.
A wise rich man would have plenty of stuff on reserve to pay essential people, just not in money. Maybe they could work in exchange for a year's worth of freeze-dried food. A chunk of land & a house. Quality goods. Idk I just don't think it's as bleak as you say; we could revert back to a barter system, and people exchanging labor for [stuff] or a cut of the product [sharecropper].
