Somewhere in there should be the means to build a fire.   
that assumes they could figure out how to gather firewood. 
things that are second nature to some of us, even if rarely practiced are not obvious to many. I can't tell you how many times when I was car camping I would see people give up trying to start a fire and use an accelerant. I have even done it when I am in a hurry. 
Personally, I am in favor of carrying something that can make emergency fires a lot easier. When one is cold and wet and in trouble is not a good time to be practicing one's bush craft skills.
