I see your pount about insurance but would love if health insurance and medical costs were more transparent.

In some countries without mandatory health insurance, medical cost is a lot lower and simpler. If major medical emergency happens, then families usually need to take out a loan. But for regular medical issues, you save for it. This includes issues like childbirth which in America very few people can afford without insurance.

I imagine, having health or car insurances gives some sense of false security, which leads to poor lifestyle choices or driving fast, which in turn causes one to experience bad health or accidents, thus using their insurance. Which causes insurance rates to rise. And one is not directly negotiating with hospital or bodyshop, those prices rises too.
