Why are governments suddenly acting as if cash money is a bad thing that must be severely limited or eliminated?
Before we get to that, let’s distinguish between physical cash—currency and coins in your possession—and digital cash in the bank. The difference is self-evident: cash in hand cannot be confiscated by a “bail-in” (i.e. officially sanctioned theft) in which the government or bank expropriates a percentage of cash deposited in the bank. Cash in hand cannot be chipped away by negative interest rates or fees like cash held in a bank.
Cash in the bank cannot be withdrawn in a financial emergency that shutters the banks, i.e. a bank holiday.
