Unless medical care is cheap enough for everyone to always afford all the care they might require with the cash in their pockets or the money in their checking accounts, I believe my fundamental question is relevant. Since some medical care currently, and for the forseeable future, requires the time of extremely smart, talented, and highly-trained individuals, I don't believe it's possible to make it that cheap.

I agree with everything else you said though. Costs are too high and are a major reason this is so hard to solve and price transparency is a big part of the problem. A related (because it distorts the market in a similar way) problem is that most people don't see the true cost of their insurance, because they get it as a benefit from their employer. I would be highly in favor of any credible attempts to fix these issues. But that's not what I've been hearing from the party that's about to be completely in power.
