this shows a rather marked ignorance of how exactly insurance even came to be.
as medicine became more advanced (ie, moved past Doc Anderson hopping in his buggy to come give you liniment), costs began rising.
eventually someone figured out "hey, we don't all get sick at the same time."
"lets pool our money together."
"we'll all pay in. George, you'll pay in a bit more since you get sick more often"
"when one of gets sick and needs the doc, we'll pay out of the pool."
that's the origin of insurance in a nutshell....before it became a self-serving for-profit industry, with fees, "determinations" as whether you really need treatment, treatment denials, pre-existing conditions, etc.
the insurance industry exists because it, however ineptly and inefficiently, fills a need: specifically, that people CANNOT pay for their care on their own when tragedy strikes. medical bankruptcies would be even more common without insurance, than with it.
so no, you're wrong.
the way forward is not to go backwards.
the forward is to go the next step further than insurance and institute single payer or some other form of government level control.... like every other civilized nation that gets better care at half the cost .
