I'll always remember the time when the tourist town of Ely, Minnesota, USA had it's single fiber internet cable cut. Pretty much all the groups there trying to rent canoes, equipment, hotels, etc with corporate cards weren't able to do it. We were lucky our group brought cash.

A society depending entirely on corporations for currency function is incredibly fragile in addition to corporate payment services being rent seeking, privacy invading, transaction morality deciding monsters. At least in the USA.

Governments should definitely be regulating and requiring those offering paid goods and services to accept cash. And not just for paying debts.
