The old “Prepper” adage that “Two is one and one is none” makes some sort of sense, I suppose, in that if one only has one of a particular thing–tool, equipment, whatever–and that “one” is lost, broken, or stolen, then “none” is what one is left with.
But consider the transitive property of the adage. IF 2 = 1 and 1 = 0, then 2 = 0. Therefore, one could as easily say “n. . . is 2 is one is none,” and so no matter how large a number of [whatever] one has, it is equal to. . . nothing.
This is a principle that escapes hoarders.
