No, everybody does not need health care. 90% (made-up as my wife, two daughters and me haven't been to the doctor in 2 years) if not more of health related issues while you are under 40 (maybe higher) can be taken care of through over the counter medications. However, we still require shelter, particularly since we live in an area that is under 32 degrees for 2 - 3 months out of the year.
