> some people are just too stupid and they'll hurt themselves and complain about it

It's not just about stupid people. It's also about people who get deceived by marketing (i.e. all of us, in some way, at some point). It's also about the market adjusting prices so that the unsafe option will be the only option available for some people, while true costs are externalized onto society.

But the point still is, as you say, we regulate a lot of things for good reason.
