I'm not going to bother to address each of your points. YMMV = Your Mileage May Vary
As for my understanding of grounding and bonding, it is a requirement of my profession. I design/build/install server rooms, backup generator systems and UPSs, as well as wired and wireless indoor/outdoor communications infrastructure, all of which must meet code with regard to bonding and grounding.
I'm pretty sure code here dictated that my copper supply lines be bonded to ground. The copper supply lines connect to the faucet and the faucet connects to the sink.If the sink is not in contact with earth is some matter how is it grounded? I think you are grasping at straws here as you sure don’t understand the concepts of grounding and bonding.
