My mother won't install a heat pump because she claims she doesn't want to be dependent on electricity. She likes the idea that if it goes down, she can still heat her home.
It is irrational because her gas burner needs electricity to run anyway, and if electricity shuts down, she lights a wood fire, which she could have as an alternative to the heat pump.
Humans have religion-like behavior in every aspect of their life, not just God-related things.
If you haven't heard about the French pushback against the linky, a smart electricity meter, google it. You will have a good overview of what can go wrong if we force the issue on people.
