That also applies to different cultures' bathing and perfume practises, but I think we all recognise that banning those practises would be unjust.

> At this point some smokers like to bring up "b-b-but what if someone wears a ton of perfume??" but in practice basically nobody regularly takes a break to shoot perfume several times in a row into the air around them.

You've clearly never shared an enclosed space with someone whose bathing practises — while unobjectionable from a health & sanitation viewpoint — are different from your own.

It's quite rare that I come across anyone who's even close to as stinky as a smoker who's currently smoking. Besides, as a practical matter, restricting bad body odor is not nearly as problematic as restricting smoking.
