This is a false equivalency when compared with the top comment. The equivalent statement would be "only car exhausts must be captured but we don't care about the rest of the gasses."
The commenter said all gasses and exhausts must be contained, and I tend to agree that this is a good goal to move towards.
Most of the population, quite frankly, is wrong about a lot of things like this. We see that from the hate for regulation partially driven by propaganda from businesses.
As a side note, cigarette smoke is also considered exhausting waste to the atmosphere.
