Maybe even more… so what kind of cash based solution could there be? (that’s not physically preventing them from ever travelling)
It might still be possible to pay cash in fleabag hotels; I don't know.
I know that because the experience of being turned away from hotels while driving across country was why I applied for my first credit card.
Possibly you can also put down the same amount they take as a hold on the card in cash, but I've never tried it.
Last time I visited the US was in 2016 and back then my country wasn't an international outcast so I had a debit card that counted as credit in the system. I'm just curious what people like me would do these days. Or maybe the hotels I stayed at were too cheap.
Unfortunately people who simply choose to live without using credit are caught up in that too.
I avoided getting credit cards for years, but you really do need on if you travel a lot.
