I don't want the government collecting taxes from cigarettes if that means that the government has a good reason to keep cigarettes sales up. If we didn't collect taxes from cigarettes, we would have to make up the revenue from something else. Sales taxes or income taxes say. So our taxes would go up if cigarette taxes went away. A purely hypothetical situation of course, no one will reduce taxes on cigarettes.
Exactly. So if the price of cigarettes actually forces people to stop in large numbers, the government will have to go after something else to replace the revenue. (They probably already have in some places.)
