That's not the relevant part of the comparison: the point we were talking about is that there are plenty of examples of things where society uses regulation rather than expecting most individuals to make good choices all of the time.
Where the impact of cigarettes is relevant is in the discussion of how _strong_ a particular regulation should be. A deadly threat certainly warrants stricter rules than something minor, just as we do not enforce zoning violations with the death penalty.
If there's a specific policy proposal you could talk about whether you think it'd be effective or overkill but instead you appear to be arguing that there's no need to even consider the range of policy options.
