When the smoking ban was planned, it amused my how the government relied on how thick people are (and yes, you really are in a mass) to get it through.
Because another - completely valid and maybe more relatable approach - would have been to ask the public "How much more tax overall are you willing to pay to ban smoking ? 1% 2 5%"
I bet the "enthusiasm" would have quickly disappeared.
Mind you, we could have had a referendum on it :
"Do you think smoking should be banned ? Yes or no"
