I'm not trying to criticize your argument just for fun. I'm quite interested in those mini collapses. And AFAIK from YouTube and similar evidence, most people choose USD. Perhaps the super wealthy have the luxury of holding gold and bitcoin, but the common folk choose USD.

Probably as more to do with savvy and future-orientation, than wealth, but those things correlate.
You have to look at their personal monetary velocity. If someone only saves enough money to cover a month's or even a year's worth of personal consumption, then he won't care about SoV, because he's using up the trading tokens quickly or could dump them fast by buying an expensive consumption good, like a car or a laptop.
But someone who traded Lebanese Lira in 2019 for USD, and then saved it, is now down 20% in purchasing power, over gold. Not bad for a trading token, but that's a fifth in 4 years and USD inflation has barely even happened, yet. How will they feel when they start losing a fifth every year or even every month?
At some point, you have to wisen up and see the USD as the Last Viable Trading Token and start exchanging it for durable goods, or you're just being silly.
If they all have USD, now, then they can easily trade in those USD for something harder.
