This is *not* correct in any respect.

There is no guarantee that the electrical system's grounding electrode, and
the metal water piping, are at the same potential unless they are bonded
together -- despite both of them being buried in the ground. Electrical
resistance in the earth is not constant, and in fact can vary widely even over
short distances.

I repeat: the *sole* reason for bonding metal water piping to the electrical
system's grounding electrode(s) is to ensure that the water piping is at the
same potential as the electrical system's ground, so that the water pipes
cannot become live in the event of an electrical fault.

Google is your friend, and educating yourself on this topic should be easy.

It's time to throw all their damned tea in the harbor again.

So, my question stands:
For the same reason that you ground the water pipe so that it is not
energized, do you need to do the same thing to the gas pipe source?

Again I am interested both in what CODE says and what is the smart
recommendation even if not required by code.
