I don’t like this explanation- while potentials are useful calculation tools both macroscopically and quantum mechanically, fields have unique values whereas potentials have non-unique values. It’s not clear to me how to compare those two benefits and decide if one is “more true.”
Immediate thought: Why not just regard the potentials as actual elements of a quotient space? :)
