You make some valid points and I tend to agree with you, but the waxed cord in paracord offers redundancy, which I favor when it comes to a crucial activity like fire starting.

It has been many years since I have faced a significant challenge with fires. Twenty years ago, I adopted canister stoves, which are fine for moderate to low altitudes. But if I am ever up against it, I want lots of options.

There are numerous alternatives to pcard; one of my favorites is braided mason's twine, significantly lighter and strong enough for moderate uses - clothes line, lashing, and the like.

Funny that no one has mention pcord bracelets, which I consider one of the dumbest ideas ever....
