Technically it’s not “their money” but that’s just a term I use to refer to all things fiat because at the end of the day, even cash is govt issued and gvt controlled. Granted it gives you more financial privacy than plastic, & that’s definitely a good thing, but it’s still going to be worth less tomorrow than it is today. On chain btc’s biggest problem is that the on/off ramps are kyc’d and most people today grew up in a kyc world, thus they consider it normal, but your point still stands.

Fiat is a shitcoin for saving but for spending, cash is still king as far as I'm concerned. Never hold more than a month worth of fiat and you're fine.
True but the screws on cash are tightening by the day, given the push to go cashless that’s happening right now coupled with a suspicion first approach banks take someone wants to withdraw significant amounts of cash that are well within BSA thresholds. I envision a future where we have btc cash that isn’t central bank issued.
