People have amazing ideas. The main problem - I won't call it a problem, let's call it a roadblock - is if you use the analogy of a convoy of vehicles going to help a distress situation: they have all the resources needed (food, medicine, everything they need), and as the convoy is traveling, there's a rockslide. You can't get through the road. What good does any of that stuff do when you can't get it to where it needs to go?
