Do we really need West and South when we can use negative North and negative East?

We could use one, and assume we’re operating in the field of complex numbers:

1 N = North
i N = West
i^2^ N = South
i^3^ N = East.

And we could use the complex modulus to indicate distance or speed... or we could map the Riemann sphere onto the surface of the earth and use a single complex number to indicate location.
