I think you're missing the point. This is presented as a last resort method - just knowledge to have. We're glad that ya'll are always prepared with exactly what you need at all times. For example, what if your megabuck winch breaks and don't tell me it can't. Or say your electrical system shorts out - a tree limb falls on your rig or you're caught in a landslide or flood and suddenly your world is turned upside down. It's just smart to have the knowledge of something up your sleeve for primative, 3rd world or emergency conditions. That's all this is.
