Take the "Ship of Theseus" example given earlier one step further.
Is it rational to consider an electron to exist and travel along a trajectory, knowing that at the same time virtual particles exist?
We could assume that in every instant a new electron and positron arise from empty space, the positron annihilates with the existing electron, and the slight gap between them is the reason we now see an electron in a slightly different place.
Movement is then an emergent phenomenon of virtual particles. Is it still real? Of course it is. This is simply a case of multiple realizations. There is no reason to see one or the other view here as more real than the other, and it is perfectly rational to accommodate all the equivalent models of the same thing at once.
