Huh?  Much rural electrification was (and still is) carried out using the earth as a conductor.  Building codes do not apply to electric power distribution and are irrelevant anyway to your assertion that the earth cannot be used as a conductor for AC power due to resistance.

I2R losses are constant for a given current.  Raise the voltage; reduce the current and efficiency rises as the loss decreases.  Or keep current constant; just raise the voltage and efficiency also rises as I2R loss becomes a smaller percentage of the equation.  The whole point of all electrical systems is to deliver power (work), not current.
