But sadly also a lot of not-stupid people who sometimes need to (or would benefit to) borrow on short notice, and it's better that they're doing that on a credit card with protections and that they can pay off. I've been both: easy credit in my youth ended up with me racking up a lot of silly debt that I had to spend several years living frugally to pay off, but also now that I'm much more financially secure, having some credit cards that work as a very cheap line of credit if I'm having a liquidity crunch is also very useful.
