Serious question: was needing two wires holding us back?

  Presumably, if you one use one wire, you will save half your money.

    Best case, I'm sure there are economies of scale.

    Not only that, but if you have two wires at a high potential difference on poles, you have to be careful to keep them separated, even under adverse conditions e.g. high winds. Presumably, ensuring adequate clearance between a single wire and the ground is comparatively easier.
