I actually really support your theory even tho it is a bit coiny.
coins unlike paper wont just wither away as fast as bank notes and have at least some real world value thru the metals they are of, even tho they are not as rare as gold or silver.
i also dont belive in fiat money and thats why i shift all my savings in different assets like crypto and gold,maybe theyy save us from the breakdown, but if every thing goes down crypto will also fall.
but i dont have a better theory how to save us from that, i just hope in crypto.
As much as I like some of the Crypot's, I don't think it will be the Crypto's that save us... Most people have a little Coinage laying around their houses and cars they'll be able to use in a pinch, but how many people have Crypto's, Gold or Silver...??? Naturally, Gold, Silver and possibly Crypto's will be very nice to have on the "Other-Side" of the Collapse, but it will be Physical U.S. Coinage, acting like a Bridge, to get us there...
