I think being able to make a fire is fine. but making a fire without some sort of ignition source is not useful in general because people don't practice it enough to be useful in a crunch. I can count the number of times on one hand I've lit a fire without anything. I used a bowdrill made with my bootlace. three or four times in good conditions, and once in bad conditions for giggles. It took me 2-3 hours to make a decent bowdrill and board to where I could even try. I did it just "for fun" on an afternoon of car camping. If it were bad weather, and miserable conditions, I'd have been screwed. It serves only enough to convince you that you should really take two bic lighters and a wee pack of backup matches in different places.
