"we can say a "ground loop" is formed whenever two or more grounds are at different potentials"
I don't think so. From Wiki, "A ground loop is caused by the interconnection of electrical equipment that results in there being multiple paths to ground, so a closed conductive loop is formed."
Closed.
Two components with ground pins connected to different grounds, whose grounds are electrically connected e.g. with a shield, forming a loop. Or, a line inside a balanced cable connecting the grounds of two pieces of equipment, plus a shield also connecting same, forming a closed conductive loop.
"What would be the purpose of running all the grounds through the pickup arm and cartridge?"
Exactly my point.

I think that this addresses your concerns as well.
Now let's return control of this thread to the OP, don't you think?
