The potential can exist. It's like asking how gravitational potential energy can exist on a flat surface. It exists, it just doesn't do anything because there is no derivatives, meaning no force. The special thing here is that apparently this is not always the case. – Ofek Gillon Dec 25 '19 at 19:17

If the previous answers are wrong, then e.g. use a bounty for better answers rather than asking the same question again in a new thread. – Qmechanic Dec 26 '19 at 10:43
