The idea of cashless stores that only support plastic and other non-cash ways of paying is, for me, not a problem. I only pay cash when forced to; being forced to keep a supply of cash for various purposes is, for me, a PitA. It’s far easier just to swipe and be done with it, paying my bill at the end of the month.
In my privilege, I never considered that such a shop might be a problem for the not-insubstantial number of poor people who don’t have credit cards, or for whom the charges on a debit card are significant.
At least not until I read about cities that are beginning to ban such arrangements, and why. Which, on reflection, makes a lot of sense, at least as long as we’re a society where some people have to use cash.
