Is There a Cash Society?

I imagine a cash society can't be great for local business either. If everyone is shopping on Amazon, we all know what happened to bookstores in the early 2000s when Amazon took over a book selling online. What do we think society would look like if it was fully cashless? Is there a kind of vision of the future in which we no longer have any high street, and we move entirely to an online system using digital currency only?"
