Good tie in to the health care debate: I don't give a damn how unsafe you want to make your life as long as you don't show up at an emergency room when the inevitable catastrophe happens.
If you intend to make use of the emergency room, then you'd better have fully paid up health insurance.
But the odds are that you're also the overconfident idiot that thinks he won't need health insurance either.
So, since the sane among us don't want to fork out for your stupidity, it is easier to guard (somewhat) against your ability to incur costs on us. Thus seat-belt, airbag, helmet laws.
And yes, American table-saws are extremely unsafe. Heck, virtually none even have riving knives (required in European table saws), which means there are a significant number of standard cuts that can't be made with the saw guards in place: ie the saws are designed to be unsafe for normal use. Table saws cause more industrial accidents than any other tool, and maybe this type of judgement is a wake up call to the manufacturers.
