Once it becomes the recognized duty of the public to provide for the extreme needs of old age, unemployment, sickness, etc., irrespective of whether the individuals could and ought to have made provisions themselves, and particularly once help is assured to such an extent that it is apt to reduce individuals' efforts, it seems an obvious corollary to compel them to insure (or otherwise provide) against those common hazards in life. The justification in this case is not that people should be coerced to do what is in their interest but that, by neglecting to make provision, they would become a charge to the public. Similarly, we require motorists to insure against third-party risks, not in their interest but in the interest of others who might be harmed by their action.
I, for instance, would support choice in social insurance providers (i.e. a market-based approach).
