>Plus cash is just so much more convient and faster.
You mentioned "puritanism and censorship" as your main issue with cards (and I assume with other digital payment systems), but to the best of my knowledge that's only an issue with online payments, for which cash isn't really possible at all. Unless you feel that sending bills in an envelope to some postal address you see on a website to be fast and convenient.
When I pay with cash the transaction is settled in literally 15 seconds. When I pay with a card it takes days, involves dozens of people and many capital and mantainance heavy systems which are extremely fragile. Additionally the digital payment services provider will take their relatively large cut so the process of the transaction can drag out over even longer times and greater costs. With cash you pay only the cost and tax and you need not ever think of it again.
The experience of using cash is very simple, fast, and reliable. In the future digital payment systems may become those things but unless you're in an urban area they currently are not. Your experience of using digital payment systems in person in, say, a coastal megalopolis differs significantly from using it to buy a shovel at a hardware store in a small town. At best (with credit or debit cards) it's almost as convient as cash, most of the time.
If I want to exchange value with another human person cash makes it easy and simple. It is far from easy with digital systems involving arbitrary third party corporate persons.
