There are temperatures below which a heat pump doesn't work at all. No amount of insulation can fix that. Not a lot of people live in places like that, but they do exist.

heat pumps don't need to pull heat from the outside air, they can pull heat from mass walls and shallow geothermal all winter long.
it's just engineering
