>There's a pretty huge asterisk to all that. Health insurers are adept at neatly sidestepping any obligations
This might sidestep some obligations, rightly or wrongly. They clearly do not sidestep "any" obligations. The amount of money spent on healthcare claims (medical loss ratios) is public information, available in their SEC filings. It is required to be 80% or more by law.

Every state government has an insurance regulator that also has to approve insurance prices, which are based on the cost of claims. The regulator is not going to let an insurer increase premiums just for profit.
Also, the non profit and for profit insurers have similar premiums, with the for profit insurers having ~3% profit margins or less, indicating a highly competitive market where the revenue is barely covering costs.
Shareholders aren't making any money either (10 year returns lag SP500):

Finally, the fact that Buffett/Dimon/Bezos tapped out on creating a competitor should really drive home how little the profit potential is in health insurance, and any less "sidestepping" of obligations would lead to higher premiums.
