A simple proposition for sure... but if it was true, why does the rod need
to be 8' long?

The only way that the ground terminal is a 'true zero voltage reference
point' wrt the larger ground mass at RF is that if the connection to the
ground mass is of zero length, and that isn't true either above or below
the ground.
