As much as I agree with you, cash is unfortunately already well on its way out: in many EU countries (Italy, France), cash transactions above 1.5k euros are illegal. For example, buying a car cash is illegal. The US won't be far behind, imho.

For small transactions (eg buying a loaf of bread), something flipped in small business owners minds: they used to hate plastic for small stuff, and I can increasingly feel that today, it's the exact opposite: people let out a small sigh of annoyance when they see you pull out your coins.

This is a freedom almost as important as free speech that's slowly and silently being choked to death by big govt and not a single so-called freedom fighter out there, be they on the left or on the right of the political spectrum is picking up on the significance of the issue.
