This specific charge was not of a person wearing a health-related face-covering, but the law is supposedly motivated by the supposed anonymity of people wearing masks at pro-Palestine protests:

> The push to ban masks in some public settings began in June after some pro-Palestinian demonstrators covered their faces during protests.

... and often at those protests, people do wear KN95 and similar masks. In those contexts (dense crowds of people shouting) on its face wearing a mask for health-related reasons does not seem outlandish. And some organizers, specifically trying to make events accessible to people with elevated risks, have advocated masking so they can have more people participate. So while this particular person was wearing a ski-mask, I think it's disingenuous on your part to pretend that mask-bans aren't related to health-related masking.
