Of course I would expect people to carry catastrophic coverage. And your case with a broken bone would qualify for a catastrophic event. But if the majority of healthcare purchases are driven by 300 million people seeking the lowest price for Vicodin, no one would be able to charge you $1,000 for vicodin even if you were going through insurance for this particular incident.
>And pretty quickly a risk pool means someone has to decide how much that pool should pay to help treat a particular injury... and you're back to where you started.
Not someone, EVERYONE. Each individual person must decide for themselves if they want to try pay a middle man insurance company some profit every time they get the sniffles or if they'd rather deal with that on their own, save money, and just get catastrophic coverage.
All of these things you're concerned about... we have an entire history of the healthcare industry before the New Deal where we saw how low healthcare prices were. We distorted the market with New Deal regulations putting caps on salaries, so companies started offering healthcare to employees. We can undo the damage done by the New Deal without getting all authoritarian about it.
