The biggest oversight is your neglect of insurance, as opposed to care.
There is an information problem in selecting insurance, as well as in selecting care/providers.
More important, however, is that insurance requires an open-ended commitment from the insuror -- over and above some limit in terms of your out of pocket/copays/coinsurance, they have to be on the hook. Otherwise it isn't insurance. Once they are on the hook, there is no spending constraint on providers and patients. The system must be near-universal, and even if it is, spending will grow rapidly, there will be a lot of unnecessary care, and it will increasingly burden the public sector.
Arguing against the free market position is pretty simple, IMO. With individual insurance, anybody who needs care will not be able to afford insurance.
