"That staple is 12.25" away from the box"...
I like that example. I got caught with 2 plugs 12'2" apart, because, "You don't expect the inspection department to give you two inches, do you?" Since then, I haven't given an inspector an inch, either.

Anyway, on topic, around here everything must be approved for it's use. We get away with using a conduit strap on cable, because it's approved as a support. I doubt that a piece of wire is rated as a support. If you allow the cable as a support, do you require a minimum size - like #12awg for 3/3? How would an inspector word that rejection notice so it referred to the code?
