True, but if the heat pump is designed to operate in very cold weather the minimum efficiency is 100% (backup resistance heating), so you will always at least break even versus pure resistance heating. Discounting equipment costs of course :)
Also, I've never seen a building (in the U.S.) that relies on electric heating if temps in the area will get much below 10°F (-12°C). At that point, it's always natgas/propane/fuel oil/wood.

But the heat pump has a "outside" part, where there is a fan and other electrify using stuff. Can you not risk that more heat is generated outside than is moved inside?
