Ideal for emergency use only IMHO, It's not exactly 'green' so personally I would only ever use it in a real life or death situation.

Its all camping after all - your level of self imposed hardship is up to you
......got a piece of inner tube in the bottom of my zippo case or wrapped around my clipper lighter
Another use for it I've used for donkeys years is to straighten fishing line when it kinks, pull the line through a small piece of rubber and yer straight, sorted.
with wax it will last ages.
Inner-tube is easier to get hold of though
