A lot of the exposure probably happens in childhood. They might never have developed asthma without exposure they didn't choose or control. Plus it's not like people are likely to die because of lack of gas stoves, most likely the opposite because of potential safety features in induction. I'm not sure how much regulation is appropriate here, but I sure wouldn't want to use gas every day by choice. It looks cool, but it's also pollution in your own house, and if anything goes wrong you might not be able to fix it yourself because of safety and legal requirements.
