Actually, the utility transformer IS ground tied, but there are no household disconnects or breakers there, so it is only for atmospheric balancing. The N-G bond needs to be at the panel, so a breaker will trip if any shorts to ground occur.Ya, I sketched it out. The N/G bond allows utility power to flow back to the neighborhood transformer which is the source. I was thinking that the transformer neutral was grounded at the transformer, guess it isn't.
Of course then I was unsure as to why the actual ground rod is necessary but that is for lightening.
