This isn't a "nanny ruling," the law that was struck down was a "nanny law." I don't need the government protecting me from a doctor's questions. If a doctor asked me (or my children) about gun ownership, I would refuse to answer. If the doctor persisted, I would find a new doctor. No government intervention needed.
You are assuming that the government will allow you to make those choices. It is not at all clear that you will have those choices under Obamacare.
