Lifestyle choices are not a function of government even if those choices result in shortened lifespans, poor health, poverty, or other "negative" outcomes. These are not externalities and are no business of society. You might say that sick people cost the society money. But the answer to that is not that people are sick, it's that someone has decided to spend money on those people. Of course this approach doesn't put more power into the hands of control freaks, so it'll constantly be fought.
> But if nothing else, the government (at all levels) should be sure not to promote and fund profoundly unhealthy habits over healthy ones.
Agreed. Government should not feed false information to the people.
