> Business are legally required to accept cash.

If you're in the US, this isn't true. Businesses are only required to accept cash for debts, i.e. where you pay after services are rendered. That's why dollar bills specifically say "This note is legal tender for all debts, public and private."

The gas station can refuse your cash payment for a candy bar because there's no "debt" yet. A restaurant can't refuse to take cash unless they make you pay before they bring you food.

It's not common to do, especially since cash is so easy and cheap to handle, but it is legal.

> Covid adds a bit of friction to this but I have yet to be refused a transaction because of a cash payment.

Earlier in the pandemic, most places near me had signs up that they weren't taking cash because of COVID.
