Now isn't the whole purpose of the rod to actually equalize the potential of your neutral/can bonded service with the earth around it?

That would be nice but it is not possible.

If you are not actually standing in contact with the rod you will be at a different potential than the enclosure.

I hear you Roger, but my inspectors still approve one ground rod on a 400 amp residential service. I have discussed this at length with the inspection department, but the building official said " we can't just make them drive two ground rods". To which I replied "not until you start enforcing the electrical code". To them I am just a smart aleck who doesn't even come close to their knowledge of the code. The reason I was in the meeting with them in the first place was because of another of their classic quotes. "We don't recognize a foundation ground". I now tell them every chance I get that when they adopt the 2005 code they may have to recognize a foundation ground. Maybe I am a bit of a smart aleck.
