Is health insurance equivalent to health care? My answer: No; at least not in all cases. What the ACA appears to do, in my opinion, is foist health insurance onto as many citizens as possible. That's good for the insurance companies but what does it do for health care? Probably nothing much, especially if you consider the significantly increased demand for health care placed on existing providers.
Whatever replaces ACA, if it doesn't emphasize health care rather than health insurance, it's probably not going to be significantly different.
