I'm fortunate to live in a populous area of a state that wholeheartedly adopted its own exchange. There are plenty of good choices available. When my employer ran out of money and went out of business a few years ago, I could afford a plan for my family that was far cheaper than COBRA. We got affordable health care through the exchange until I could land a regular job.
But many people don't. There are a growing number of markets that aren't offering ACA plans at all. Other markets are seeing 20% y/y growth in their prices. In short, the ACA is failing. You can be mad about that all you want to, but it doesn't change the fact that being afraid of the ACA is totally rational.
