obamacare dictates to the insurers what they must cover so try again.
It doesn't "cover" anything.
It specifies the coverage that makes it adequately likely that your health costs will be covered by you, and not be defaulted to the rest of us. It holds you responsible for your own costs.
Why does that make you squirm?
Because 'adequate' is decided by regulators and their buddies in the insurance industry, and not by the people being forced to buy the shit.
Unfortunately, there are irresponsible and/or misinformed people in any population. There are a huge number of examples of where responsible and informed people have to help them avoid the consequences of that to themselves (medical bankruptcy) and others (medical bankruptcy or inability to pay medical bills).
If you have a plan to eliminate these irresponsible and/or misinformed people from consideration, let's have it.
