Well, you've got to admit they have an uphill battle: smoking is smelly; the smoke permeates clothes, hair, furniture, and carpets

Societally-approved behavior can change over time. Used to be, being a functional alcoholic was no big deal, for example. Drinking and driving used to be no big deal. Over time, society has decided that certain types of behavior is not acceptable and laws/rules have come about to deal with that. Since no legally protected rights seem to be at stake, there's really nothing preventing the majority from imposing these rules on the minority.

Stunned silence.
