So you and some others
claim.

I accept that, but it's not a particularly large amount.

So why ruin its NOx emissions by disabling EGR  |
Because the engine functions better and lasts longer. And it gets better mileage. Yes there are tradeoffs, but I am not convinced NOx is a serious problem. Acid rain is not an issue in the front range of Colorado, smog
was much worse than it is now. My understanding of acid rain is it's caused mostly the sulfur from coal plants.

If we all throw the emissions control gear out of our cars, motoring would be a lot cheaper for all ... Bonus.
Or not ?
We'd also be going back to the pollution levels of the 50's-60's-70's.

I never advocated "throwing out all the emissions control gear from our cars", so please don't put words in my mouth. I am not ripping out the catalytic converters from my vehicles, and certainly not disabling EGR or evaporative controls on my gasser. I also never advocated making modifications solely on the basis of cost savings either.
If you are reasonable I think you will find my actions are proper enough, regardless of whether you agree with me specifically. If you want to be a purist, I'm not interested in your judgment. You will only invite the same on yourself.
