Defining roughly what lies in the public sphere and what lies in the private sphere would seem rather crucial to me. Governments aren't particularly inclined to make that separation on their own, since they must settle problems ad hoc, and because historically there will always be this or that set of people for whom the topic to be settled, whatever it is, lies in the private sphere. Indeed, it's reasonable to assume there will always be ample demand around for the government to take on the "private sphere."
