So if it's literally all about money and not health, why do governments introduce cigarette bans / restrictions?
It's a love/hate relationship.
Governments love the tax revenue that smoking generates but they hate the smokers. I honestly can't give you an answer as to why smokers and vapers are treated like pariahs - the only thing I can suggest is it's because we're different.
We stand out from the crowd in a very visible way - we continue to indulge in a habit, despite the health risks and the government insisting we should stop.
We're not 'normal' citizens - we're a disobedient (though harmless) counter-culture that non-smokers or ex-smokers feel is anachronistic and shouldn't exist any more.
And despite all their best efforts and billions of dollars invested into encouraging people to quit, we're still here, still enjoying our nicotine with no intention of listening to them or obeying them.
Guess that pisses some people off
