In the past 30 years, basic financial transactions (buying groceries, a meal, a movie ticket, etc) have shifted from (my estimate) probably 90% physical (cash and checks) to 90% electronic (cards, apps, EFT, Paypal), and most consumers prefer the new methods.
Some rough edges need to be worked out, but I would not be surprised at all if over the next 15 years, a decent number of companies start paying employees via stablecoin. And once that transition happens, it's not much of a leap to allow employees to decide whether they wish to be paid in a dollar-pegged currency or something else entirely.
