That's fair, but personally I am much more comfortable with the government regulating things which actually have chemicals which cause people to be addicted to them (cigarettes, hard drugs, etc.) than services which people can get addicted to. The fact that their is actually a chemical in cigarettes is the critical difference, to me. Maybe psychologically there isn't much difference, but that's where I draw the line personally.
