So did things like being rejected for coverage due to "unexplained weight loss" when I was dating and trying to get into better shape and had lost a whopping 5 pounds over a few months (as noted in the application).
From my more cynical older viewpoint, I was never going to get decent coverage on the private market and that was simply a viable reason to present for rejection.
Sure.
It shared the market with a lot more useless health insurance, and whether the useful plans were actually available to any given individual was not necessarily a function of how hardworking and conscientious they were.
Useful health insurance existed before the ACA.
