Well, but that&#x27;s why we talk about it and decide this democratically.  Where are we drawing the line on what the government does for public health?  Right now, we&#x27;re not banning sodas, but a tax on them seems like a relatively benign way to curtail the public health hazard sodas represent.<p>It isn&#x27;t a slippery slope so much as a discussion we have as a people.<p>After all, there&#x27;s very little debate over how much right the government has to nanny-state us with all these traffic lights and traffic lanes (where in the constitution does it say that the government can tell ME where and when I can drive my car??), because we&#x27;re generally OK with that kind of government-dictated restriction of freedom to move.
