I mean, it kinds seems inevitable to me. Books has become e-books. Cash is becoming digital transfers. China has done it. The west is mostly doing card-swipes. One day, that transition will be complete, and cash would be phased out.
What happens then? Think like the power outage in Spain recently. Some people had cash. But in 20-40 years. There might not even be any cash in existence. What then?
What if, instead of a few hours, its a few days? Or weeks?
I guess riots break out all around the world?
(Seriously, has none of the politicians ever thought about this? Where are the backups? Are we just going full “YOLO” on the reliance on the power grid?)
I know its not the same thing, but we’ve completely done away with the barter system. Way back in the days of yore people would be swapping things for things, and then money came along and they were like “whaaaat you want to take my stuff in exchange for a few little discs?” And now it’s totally normal.
We have not completely done away with the barter system. It is just less visible.
I worked on a farm for a while that grew vegetables, and bartered some of those vegetables for other products from neighboring businesses. We got a pallet of apples in exchange for squashes from a local orchard, and seconds frozen pizzas in exchange for veg for pizza toppings from a local restaurant. We even bartered labor. There was someone who came in every week and spent a few hours cleaning and organizing the tomato cooler in exchange for some tomatoes that were on their way out.
In each case it was mutually beneficial for all parties to exchange in kind without using cash.
So while bartering is not common, it still exists.
I’ve been at some festivals where the bartering system was alive and well! People would trade beer for camping chairs or a volleyball for some duct tape. Good times :)
