The article doesn't explicitly mention that handling cash as a business isn't free and comes with its own set of problems. I can understand why one might choose to eschew cash as the cost is greater than any lost business these days when most people have/prefer card or mobile payments. Contactless payments have gotten very fast, low friction, and widespread.

I'm not taking a stand one way or the other and I acknowledge the problems of cashless-only, but I understand why businesses are increasingly often not finding the cost of dealing with cash worth it.
