Everyone with a grill will have to enclose the entire grill area with an airtight, filtered forced-air ventilating system, making it impossible for anyone not in the 1% to afford one.
Like I said in my post, there's no way they could enforce any of this. Everybody could just roll the grill into their garage, open the door about 1/3rd of the way an grill away. How they going to catch you? It would require too much money to try and enforce this in any significant way.
