This is terrible advice.
The chance that you are the victim of a serial killer is so vanishingly small as to be not worth considering. Therefore if you have an intruder in your home, they are almost certainly after your property.
I would hope that any moral human being would not value property over a human being's life.
Therefore the best outcome which preserves human life is to simply let the intruder take your property and leave. They're almost certainly in a hurry to do so.
Involving a firearm escalates the situation unnecessarily and raises your own chances of death from very very unlikely to probably 50/50 (stat pulled from my butt).
If, on the other hand, you do believe that lethal force is justified to protect property then you have a miss aligned moral compass.
