What makes you think that preppers will do that? A television show? Or real-world experience with preppers?
Personally, I've cooked for neighbors when power was out after storms in the neighborhood because I had the equipment and skills, and quite a few of the neighbors are geriatics.
Prepping is about maintaining communities. God calls on us to be of service to others. I can't do that without being prepared, myself.

I’m hip. During Sandy, our neighborhood was without power for 8 days. After a few days, our neighbors started coming over in the evenings to sit by our fire to warm up.
We had awesome fireside chats.
