Sure, but the increase of granularization in insure in general was mentioned in the comment I responded to.

You could say there's a spectrum, between stuff like healthcare and genetic diseases, and someone insuring their pinky finger not because they need it, but because they're vain and think it's an astonishingly pretty finger, and they're just that rich. But somewhere on that spectrum, there are also families that lose bread winners, and I don't see why solidarity wouldn't also apply there.
