Sorry, but that is an absolutely incorrect statement.
Current CAN flow through a conductor without any potential difference across it, when it is part of a circuit that has current flowing because of the other circuit elements. In fact, this is the definition of a conductor (in the normal sense).

Given the context of the answer ie why something isn't something happening in a simulator and your stance on not confusing the OP, why then do you write a paradoxical statement that can be proven mathematically to be false and then allude to mysterious elements that are not part of the current( ;D) problem
Ltspice shows zero current if you try to parallel "wires" and spice in general does not simulate connection properties. If you want a wire in your sim you'll have to model it

Apologies.
My response was based on the real world situation, where I now see you were talking about "why something isn't something happening in a simulator".
Apologies to the Op as well.
