We used to have a system where people ejected sewage into the street, too. It’s telling that you equate air pollution to sewage, and then imply that pumping it into the street constitutes proper disposal.
If you still don't get the parallel, let's move one step up: all greenhouse gasses produced from your energy use in your apartment have to stay in (including those from coal power plants, grocery production and delivery...). Sorry, no opening windows for you to get your own CO2 out to other people.
My point is that air is a shared resource, and thus a shared responsibility. But someone turning the narrative extreme does not help drive any solution forward (I am reminded of Stan's dad Randy getting a Prius in Southpark).
