I think we agree on most of this, but we're coming at it from different angles. ;-)

My emphasis:

>>The Kaiser S&P analysis shows that the markets under the current laws were stable, which contradicts what the Republicans have said.

"Under current law" is code for "as long as subsidies and bailouts continue at current level and are extended every time they expire." IMHO the MSM can do better than this: a layperson will think they know what a "stable" business is.

Consider Tesla, proud to call itself an electric vehicle pioneer. Is Tesla "stable" if it relies on subsidies of many thousands of $ per vehicle? The US subsidy has been $7500 per vehicle. Where such subsidies are granted, are they expected to be perpetual, or to encourage/incentivize the risks and costs of a new paradigm?

FWIW, in 2017 numerous nations are reviewing Tesla's eligibility for subsidies. The GOP proposes to end subsidies, as do Norway, Germany and others.

Is it not reasonable that purportedly private businesses cannot expect to have losses covered by government in perpetuity. "Stability" surely ought to mean you're paying your way and satisfying creditors without artificial bailouts by the taxpayer. Otherwise the subprime mortgage debacle could be called "stable" because the taxpayer bailed it out too.

If US healthcare insurers rely on billions of $ annually, it's not a private market, it's a public-private arrangement and at some point you have to ask why the insurers aren't run as co-ops or mutuelles as they are in quite a few other places- staffed by the same caliber of people but with surpluses plowed back into the fund rather than hoovered as dividends. What does the status quo offer the nation that's better than this?

There is US precedent: both Medicare and Medicaid are publicly funded healthcare. In hindsight, the last administration might have been smarter to expand Medicaid more aggressively and also expand Medicare. Far more difficult to take that off people, though the Supreme Court helpfully made the Medicaid expansion optional and the GOP proposes to reduce its funding without much political fallout so far.
