Might you need both? From what I've seen, dig deep enough in a particular hole, be it theoretical physics, statements about God, etc. and you get the paradox that two different things imply each other mutually. You can't have one without the concept of none, and you can't have none without the concept of one. See Godel's incompleteness theorem, the particle vs. wave situation, etc.

Are you saying that this concept is mostly absent from the Taoist texts you've read?
