Gas stoves fill the air in your home with particulate matter (pm), which has been found to increase cancer risk in the long term.
So next time you buy a stove, consider choosing an induction stove.
Btw, gas stoves being better or faster than induction is a myth. They have certain specific advantages, but they are actually slower.

A $50 dual burner camp stove solves that (or even cheaper, a $12 single burner backpacking stove if you have less space).
While you’re correct in general, in places where the power is out for a week, a camping/backpacking stove would be ill-suited to the task of keeping multiple people warm and fed. Especially in a house and not an apartment.
A gas furnace won’t keep you warm when the power is out, either. I will say a camp stove feeds just as well as a regular stove, after all, how often are you using more than 2 burners simultaneously?
