Bare ground in conduit

[SG-1]

If the bare EGC and pipe were bonded at both ends, would you have arcing between them?

I refer to Soares Book On Grounding & Bonding 10th Edition Chapter 11 Clearing Ground Faults & Short Circuits page 207 sixth paragraph on that page.

The Code permits an EGC to be bare or insulated. However, if the conductor is bare, there can be arcing between the bare conductor and the interior of the conduit at points other than the point at which the ground fault occurs. This is due to slight differences in impedance between the raceway & the wire, resulting in potential differences that can result in arcing. Such arcing can damage the phase conductors without adding to the proper functioning of the ground fault circuit. That makes a strong case for the use of insulated EGCs where installed in a metal enclosure.
