Ok.
Ya got me. I exaggerated. Good catch. :-)
There was one time when my Buick needed to have its transmission replaced. Having no other car, and working at a place that would take 2 hours to get to via public transportation (vs. 20 minutes by car), I needed to rent a car for a few days. (No, the dealer didn't offer me a car.) CC was required.
There was also a time when I went on a job interview to another city. The company arranged the flight and arranged to have a car reserved for me, but I had to pay for it with my own credit card. (They reimbursed me a few weeks later.) People who go on job interviews in a new area will likely be in similar situations.
Yes, there are millions of people who get by without credit cards and probably a few million who don't have bank accounts. They must have options to get paid. But for most of us, and for an increasing percentage of the population, electronic funds transfers are nearly essential.
Cheers,
Scott.
