Reality is the only thing that will ever repeal ObamaCare.
Faid (is that even a word?) to say it. But your right. The courts will never take down the whole thing. Their nibbling at it will only make it worse to boot. Even if somehow Congress repeals it (low to none), the Democrat or RINO in the White House will veto it, and congress will never have the will or majority to override it.
It will distort this nation in ways we can (and can't image). Health care is necessary (at least at some point) for everyone. As our healthcare system has been holding up the socialized health systems of the rest of the "developed" world, the collapse of those systems will speed up. They are starting up a s**t storm liberals didn't plan for and don't seem to care that it will.
Imagine medical "tourism" at a huge scale. No, people will stop coming here, we will be going other places. Places will become havens for real healthcare. That is if you can even get there. You may be too sick or more likely too poor. Because they won't be cheap. We may end up propping up regimes like Cuba, as it already has a cash only healthcare system for tourists.
Imagine black market healthcare. Yes, there will be illegal medical services someday, like there are illegal toilets and lightbulbs today. Single payer will make all private medicine illegal. So instead of a modern hospital, we will be going to some back alley.
That's just the two I can think of off the top of my head.
