Unfortunately one of the side effects of Obamacare is that rates have skyrocketed to the point that many people can't afford it.
There are subsidies, but the premiums / deductibles are still high enough to be basically useless for many people. Add to it that we had a mandate that you needed to have insurance or you'd be fined.
There are a lot of good things that came from Obamacare, namely the removal of pre-existing conditions and the ability to keep your kids on your health insurance after they've left the house.
But there are real issues with the program, and what many people hear when they raise them is effectively "You're just holding it wrong" to steal that old iPhone marketing wank.
I honestly don't know anyone who is against improving healthcare in the US. The main thing people are afraid of is that a well-intended change will make things worse for them.
(This is a rant at this point that I'm not even sure is responding to anything you said)
Is that really a causal relationship? What I see in the data is annual insurance premiums rising at 3-4X the CPI inflation rate starting in the 1990s and continuing to the present. The ACA was an attempt to address the fallout from this. It may not have been entirely successful in doing that, but it certainly wasn't the cause of the problem.
* Check the McKinsey study and the Commonwealth Fund study for data. In the 3 years prior to the ACA, nationwide premiums averaged a 10% annual increase, in the 3 years after the implementation of the ACA they averaged a 6% annual increase.
I will admit I didn't look at the study. Does this mean the 3 years prior to the law passing or the 3 years prior to the law going into effect?
I would expect insurance companies to start adjusting rates in anticipation of the new law, even if it hasn't taken effect yet.
