Well then the solution is to mandate a hood that cleans the said toxic gas/es out. And if we were being serious at all; there is always a habitability clause in the rental agreements which can be used to mandate the hoods where gas ranges exists. No new laws/regulations needed.

But those would be too good of solutions and spoil the current sneaky plan. Too many goal posts are shifting for justifying a performative-feel-good-climate fight (the point the top-level comment is trying to make).

There is no pure free-market anywhere (and it's a good thing). Let's not justify govt overreach in the garb of imperfect market-capitalism.
