An induction cooker may be more efficient, but if you're burning gas (or coal) to generate electricity to then operate an electric stove, it's more efficient to burn the gas directly in the stove.
With the broader societal goal of "never burn fossil fuels when an alternative exists" and "never have to build new infrastructure for residential gas again", it becomes clear we should move away from residential fossil fuel consumption. We must work to cutover individual tools from fossil to electric, and in parallel work to cutover electric generations from fossil to renewable.
The same principle applies to vehicles. I don't care that the electricity for a Tesla comes from coal today - it soon won't.
I hear the rebuttal "ICE engines are very inefficient but a gas burner is different". Yes, but the replacement need is the same, and on the timeframe that people buy large appliances, it would be best if people moved to electric ASAP.

That all said, from an air quality concern perspective, I agree the focus should be on proper venting. It is disgusting to me that so few houses and almost no apartments have true external venting for bathrooms and kitchens - why this was done in houses 50 years ago but not today should be an embarrassment to every homebuilder outfit.
