Went camping at a popular local park on 4th of July weekend. As it turns out, a hundred or so charcoal cooking fires will blanket a whole region with a thick haze even if they are all outside to begin with =/

Yes, this will happen and I am not arguing that it would not happen.

Chimney has two effects mainly: exhaust to the outside and above the buildings such that the wind can dilute it enough.
