I am old enough to remember paying bills by mailing a check or money order to a business. Paypal's convenience has made us lazy and complacent. Let GAB set up one or more USPS mail boxes for security. The US mail is inviolate. The money order can be cashed at the USPS store or at a bank with a deposit.
I, for one, would support this. Kill the Paypal and Stripe beasts with cutting off their money. https://www.usps.com/shop/money-orders.htm
