I don't think that's why he was killed.
- The 'Whatabout' argument, whatabout alcohol, marijuana, gambling etc. This is not an argument which can guide us on what to do with tobacco. If the question is, why are we doing something about tobacco but not any other X problems, the basic answer is because tobacco causes a huge burden of problems, and there are only very small upsides to smoking for an individual, and very large downsides for the individual and almost everyone else.
I think there is a lot of research showing that 'putting out health information and reasonable restrictions' doesn't achieve much. If you are agreeing that something rather than nothing should be done, why do something that doesn't really work?
Doubtful. The real answer is that public opinion on smoking has turned so strongly against it that these bans won't create enough vocal opposition. The anti-vice authoritarians only stop here because they would be eviscerated if they tried to ban something like alcohol. But we should be careful about emboldening the moral busybodies with national victories.
Bingo. The state is dictating virtuousness for our own good.
