It's supposed to be that insurance converts inherent risk into a predictable cost, but health insurance is not really doing that. The costs remain unpredictable.
Healthcare is one of THE MOST demand inelastic commodities or services. People do not say “oooh that’s a lot of money - is there a worse doctor who is cheaper?”, instead they say “100% yes I will remortgage my home and sell assets to pay for the cancer treatment my child needs.” Nobody is at the free clinic by choice, they’re there because they cannot afford or borrow to pay for better care.
Capitalism is incompatible with ‘rational consumer purchasing choices’ that apply to clothes, food, TVs, etc. because when there’s death or life altering negative outcomes, the only rational decision is to pay WHATEVER the price demanded is. Healthcare has a demand wall, not a demand curve.

I can't believe how many times I had to make this exact point to dipshits I worked with any time they uttered the term "free market".
What am I going to do in an emergency in the back of an ambulance on the way to the ER? Hey, can you guys pull over for a sec? I need to check if the current ER doc is in network. Fuuuck ooooffff.
I then recount the time I needed a non-emergency procedure (MRI for my back) which affords me plenty of time to shop around. I proceeded to call around to try to get prices (LOL) and then I got my insurance and MRI place on the phone all at once and I STILL couldn't get a solid number for how much it would cost me. Who the fuck else needs to be on the call to get a number???
No, in theory, they work like a well-funded savings account: you put in a predictable amount of money every month, and they store it for you until you need to withdraw it; with an added benefit that they would allow you to withdraw more than you have (internally using other people's money to cover the difference) under the assumption that any shortfalls that result will all come out in the wash eventually; some people overpay, some people underpay, and you invest what you have in low-risk investments in the meantime. All insurance companies work like that in theory, or at least that's what they tell regulators. But in reality, they don't pay out nearly enough to provide the consistency people need.
