With all due respect for your knowledge, Dave, your last question seems strange seeing as though you answered it yourself when you said the "ones" represent quantities of qualities.

Positive charge is "something" that is cancelled by negative charge to render charge as "nothing." The same can apply to mass, energy, space, time, and even you yourself because the particles/waves that you consist of are composites of negating forces.

My only argument is that fermions, based on velocity (not speed), can't occupy the same place at the same time as well. They are the result of +- decay through time dilation which either has a positive or negative reference frame.

I'm pretty sure that Brent is referring to keeping universal symmetry, which is promising when we consider that models based on asymmetry can't be correct - including the broken symmetry of matter/antimatter for yet to be discovered reasons.
