I live in a rural area. Electricity goes out for like a week pretty consistently every year.
I've got a propane generator, but running a stove off of it rather than just using the propane to run the stove seems silly. If power goes out for too long, I'll turn the generator off, be without electricity, but still be able to cook.
The health risks of propane seem pretty marginal to me. If I were going to try to change my energy sources for health reasons my wood heat setup would be much higher priority.
Because the thing that knocks out the power is freezing rain / snow mixes. When that's happening I conclusively prefer being inside.
And replacing my current setup with a similarly function primarily-electric setup would be expensive even ignoring my preference for being partially off-grid. Right now I don't have 220V to my kitchen at all. Decent induction stoves aren't cheap, especially with space constraints. My cookware is all appropriate for an open flame (e.g. cast iron, enameled cast iron) and while it may work with an induction setup it wouldn't be optimal there.
