But the mandate is what makes it work. If people only buy insurance when they're old/sick/etc it doesn't work as the young and the healthy won't pay into it.
Shooting people dead works really well to put a stop to their suffering, too. The gun makes it work. Without the gun and bullets it just can't work, can it?
Obviously, the real question is not whether or not the "mandate" is needed to make ACA work. The better questions are:
1) Is ACA a net gain for the industry or for the public? Remember that thing called the public option, the thing that over 70% of the public wanted?
2) What are the massive drawbacks of the "mandate" — like mandating that the public pay for the bribery of politicians (money on a loop) as well as for CEOs and ads?
