The moral is that any system which introduces price opacity will gradually increase the price of the product until the price is above what the market will bear.
Look at it this way - at the point of purchase, you are buying a product with absolutely no price information, because "the insurance will take care of it". With no price information to the consumer, there is no price discovery, and without price discovery the supplier will increase prices beyond what the consumer is willing to pay.
If all medical insurances were banned, the cost of medical will not exceed what the market will bear: it can't.
But that's extreme - how about a practical and workable solution: no private dealings between medical insurance suppliers and medical service suppliers.
You have medical insurance? Lovely - you will be forced to submit the claim yourself. When you visit the medical services supplier (doc, hospital, pharmacy, etc) for non-emergency services[1], you will be liable for the bill, and so you will have to lookup what that/those particular code/codes cost/s.
In this way the cost of medical services will actually come down, to what the market will bear.
We've seen the same thing with US tertiary education - free money introduced into the system by the government caused tuition fees to skyrocket, with all the profit captured by the providers. IOW, the price rose to what the market will bear, and since the government was the market in this case, the price rose to what the government was able to pay, which is perhaps 3x to 10x what an unemployed 18 yo is able to pay.
[1] For emergency care, obviously the claim will be submitted to you by the hospital, and you can then forward that claim to the insurance. Even better would be if all emergency procedures have state-backed insurance.
