most resistive heaters will convert 100% of electrical energy into heat. No fuel can reach that number. How can you - in good faith - make the claim that electrical heating is wasteful or expensive, even accounting for edge cases?
If anything, it is the opposite when compared to burning any fuel for heating, particularly if you are living off-grid in a rural environment. If one considers the situation in the original link - exorbitant utility fees - it makes absolute economic sense to run heating and cooling off electricity, especially if you generate that electricity.

In many/most parts of the world, the electricity you get at your house was generated by burning a fuel at a remote (to you) plant. In that case, you would have been far better off burning the same fuel at your house to generate the heat (assuming you can). Both the generation and transfer have significant losses. It's also true that if you generate it from some other source the math changes.
- jacquesm 5y agoIf you generate it using solar or wind power locally the math indeed changes: those are very expensive KWhs so you tend to be far more careful with them. Running resistive heat off a local solar installation is madness, I have never seen this done in practice, except for cooking and even then it is an expensive affair. The first thing you learn when you go off-grid is that every little bit counts. Electric heat is right out.
