Since we are heading to a world with no cash, what's stopping the card companies from doing that after there's no way back? This is why I use cash as much as possible - to delay that day.
A big thing discouraging me from using cash is how suspicious people are of you when you pay in cash. I've definitely gotten weird looks from cashiers when doing so, especially when you pay in larger bills (like $100).
Never went to CVS again, I assure you, but cash definitely has a stigma in some situations.
But with increased transaction prices, the only way I can think of is by legislation, but we know that legislation is typically reactive and not proactive. So if the CC companies go slow enough, it's like boiling a frog. And no, cryptocurrency isn't a solution to this as (the vast majority of) transactions aren't private nor anonymous.
