Health insurance is like driver insurance, not car insurance. Health costs are borne by the community in A&E if people don't pay for it themselves. That's why a mandate is fair from a social contract perspective. Some people might prefer a state that leaves poor people to die on the side of the road after an accident, but not the majority. (FWIW, in the UK, driver insurance is attached to the car (or possibly multiple cars) and is described as car insurance colloquially. Car insurance may or may not include property insurance, at two levels: damage you're not responsible for (fire and theft), or damage that you are (an accident you caused).)
