But this argument can be trivially extended to all other "social engineering" taxes. Vice taxes make you drink or smoke less? You're reducing state's expenses on healthcare, law enforcement and social services. Tax benefits for installing photovoltaics or buying electric cars? You're helping to improve the quality of life, again saving state on healthcare, and in the future, on various forms of crisis management once the climate issues start taking their toll in full.

(FWIW, I'm generally in favor of this kind of "social engineering" when done by democracies.)
