I don’t see any danger in his suggestion, nor do I think his suggested installation is itself a violation. But it is also not a requirement. Nor does it add to the safety of the installation. What this tells me is that this inspector has no idea of how grounding works.
My response would be, “Thanks for telling me what you would like to see. I have decided not to do it, because the code does not require it, because it will have no impact on the safety of the installation, and because I do not believe in wasting my customer’s money."
Of course, I would not have to live with the consequences of being rude to this inspector, and you would. So be nice, but be firm.
