In a without rule of law situation, having a RC aircraft with FPV capabilities probably is invaluable since you can scout the area without risking yourself. Of course, if you let people see it return to you, that probably would make you a huge target since it means you have electricity and technology, and if you have that, chances are you have food and water as well as weapons stored.

Either way, be it anarchy or modern day politics, you need friends you can trust and you need to stick together. The lone wolf is slaughtered by the pack.
