Insurance is required
Car insurance is required by law so that you do not get stuck with a bill due to what I did.
Health insurance is required by law so that you do not get stuck with the bill for what I did... again.
At one point I got real sick, and had no health insurance. US taxpayers got to pick up my more than $100k bill. I gambled that I did not need health insurance, and taxpayers lost.
I think that makes me a too big to fail bank....
