I politely disagree. The article seems to say that since insurance companies run a profit, they can not be worthwhile. And of course, for most people, they are not worth their money since most people never have a huge emergency that costs more than the sum of their premiums. But then, the very point of insurance is to help in case of an emergency where you can not help yourself any more. Someone once drove my car through a wall in an accident. The car was old and worthless, but the wall would have cost me 15000€ to repair had I not had car insurance. With health insurance it is even worse: You are risking not 'just' money but you very life.
