Gettng beaten up is mild compared to some of the consequences of not having health insurance ...
Certainly not if you die from your beating. Seriously, if this is all you got ....
and if you really think the government has become that punitive, it's still legal to leave.
Yes... the fallback position of authoritarians everywhere. Love it or leave it.
Seems to me that's exactly what you're saying about corporations.
Yep. You really don't see the difference? You don't have to leave the country to stop doing business with a insurance company (or an employer). You just tell them to fuck off.
Again, it's a false dichotomy and without it, your argument falls apart. If all you can offer is a 'choice' between submitting to government or corporations (or, as with ACA, both), you're not going to persuade people who think for themselves.
