Until recently, I've mostly lived in apartments or condos where a backup generator is not easy to own or operate since there are limited places to store fuel or to put a generator while running. Even if I'm ok with putting it on the balcony and running a cord inside, my neighbor may not want the generator's exhaust in his balcony.

Now I live in a single-family home and have an entire RV parked beside the house (with an on-board generator, and around 100 hours of fuel in the RV's gas tank to run it). I can run an extension cord to power the house furnace as needed, but unless it was below freezing and I was worried about the pipes freezing in the house, I'd probably just let the house stay dark and move into the RV during an extended power outage.

So I can confidently say "You are crazy to not have a backup Recreational Vehicle!". Maybe I should buy a travel trailer to back up the RV.
