Of course, this doesn't mean that a technology that provides convenience can't come with hidden costs, and the cashless society indeed comes with risks. That's where the interesting debate is IMO, but the fact that people value convenience is quite reasonable and not new.
Using cash is not actually inconvenient though.
I often find that people use the term "convenient" to mean "more pleasing to me" which is completely different.
It's not more convenient for me to buy milk from Amazon than it is for me to get it from my corner shop, it might be more pleasing if I didn't like seeing or talking to people. Those are two different things.
By contrast if I had to wash my clothes in a river it would take me literally hours of manual labour every week and they wouldn't be as clean.
It's a total non issue. You probably have a bank card or phone in your pocket or on your desk.
Some of us even use _note books_. Insane, I know.
Which you, at some point, had to withdraw from an ATM. And which slows down your transaction time at a checkout.
I do have a phone in my pocket. I would have my phone in my pocket anyway. It's great that it now means I don't need to manage bits of paper and metal too.
In a few short years or decades it will be more convenient to simply plug yourself into the wall. What then?
"We" simply accept that the real world is too inconvenient? Too resource intensive, too difficult, too ugly?
You do you, boo, I ain't down for that.
