The USD is so worthless it's stupid to try using cash on anything substantial. People with families would need to get out $300 every time they want to go to the grocery store. If you drive a gas guzzler you need to carry hundreds of dollars just for gas, unless you want to stop at the bank every few days. Cards were used as a boiling frog technique so plebs wouldn't notice how bad inflation really is. I just wonder when they'll do away with USDs entirely.
The truly concerning thing was paying with card and the gradual removal of cash from the economy and that ship has sailed a long time ago.
In 15 years you wont be able to pay cash anyway or youll pay a premium IF they even accept it.
