My meter was off the charts when turning on the gas range or oven. I didn't get a meter until after a trip to the in-laws when my wife noticed that cooking at their house didn't make her sick, but as soon as we were back home it was an issue.
We swapped the gas for induction and love it - especially the part where she isn't getting sick from using it. Our house is built very tight. The air quality meter also got me to put in an air exchanger. It was great to have numbers before and after these changes.
We had gas because I've always liked cooking on it and it works when the power is out. It was hard to give that up. Now we use a camp stove when the power is out.
I think a ban is too strong. It seems like building codes requiring a range hood that actually works could be enough.
