I remember the feeling I had back when our receptionist told us she had gotten a real estate agent license, and was hoping to make more money in that profession, and that "real estate prices can never go down, they aren't making more of it"... Just before the crash of 2008 I get that same vibe when people say that BitCoin, StableCoins, or the US Dollar will be around forever. While I'm tempted to think that a return to Gold and Silver is in the cards, I suspect that with modern markets, it'll be more than just those 2 metals, and might include MWh of electricity, barrels of oil, tons of coal, and many other commodities with a huge arbitrage market keeping trade liquid. (Much as it is with the various blockchain coins)
