Commerce Clause Allow THIS, but not Individual Mandates?

So...........you can take away the rights of every single person in America to seek state tort law remedies in state court because the public's health MIGHT be impacted because some supplier of vaccine MIGHT possibly go out of business (because they make defective vaccine).

But you CANNOT pass a law that requires someone to have health insurance or pay a $500 fine because the entire health care system is broken and 33 million people are without health insurance????

I am sort of missing the consistency of the entire Tea Bagger "Commerce Clause cannot apply" argument here....
