I certainly would not mind similar provisions in law in the US.
I certainly would not mind similar provisions in law in the US. I agree. Every time I see a sign that says "We're cashless!" I read it as "We're racist!" If the very minimal burden of handling cash is going to ruin your business, you're not a business. You're a hobby.
If you have employees, cash also makes it much (much) easier for theft, fraud, tax evasion, and so on. It's pretty easy for employees to skim cash if it's coming and going.
If the "cash" part of the business is small compared to the rest then it makes (business) sense to simply eliminate that.
I agree with you though that it has an unequal effect on different groups of people. And yes, the un-banked (and that typically means the poorer segment of society) tend to be the most affected.
