Seniors or not, the most important thing to me is this: cash is issued by the government, and can be used without incurring any additional cost. Credit cards require you to sign contract with a bank, which is a private company, that makes money on every transaction. Government should never force you to sign a contract with a private entity, for any reason, so if they ever want us to go cashless, then I would expect they provide government-issued, free of charge credit/debit card for everyone first.

But the law in question isn’t about the government requiring people to go cashless; it’s about whether private businesses (stores) are allowed to require their customers to go cashless.

Receiving cash does have a cost, it requires you to either have an employee to handle it or a machine, someone to install and do maintenance on your register or cash machine, and armored cars to transport your cash to the bank.

Only coins are issued by the government. Paper notes are issued by the Federal Reserve.
