It's irrelevant to health care but not irrelevant to when someone makes the argument that this reform is being forced. Auto insurance is forced and you don't see people largely protesting it. Most people drive cars, most people want to drive a car, a part of the 'american dream' is to be able to drive a car, most wealthy people drive cars, most people drive cars, the societal norm is to drive a car, people drive cars.
The point is though that the option is still there. And that the fact that the mandatory auto insurance is to protect the other people that you wind up hurting, not yourself.
