If virtual particles arises all the time, everywhere, wouldn’t an virtual electron-positron pair arise near an real electron; the virtual positron annihilate the real electron (as opposed to the virtual one), then the virtual electron takes the place of the real electron and becomes real itself?
Thus what is more permanent in a sense are the quantum information of the electron, as the electron which replaces the old one very quickly gets replaced itself. And in quantum physics, we calculate and represent these fundamental particles via their quantum information, it’s not possible to tag individual electrons to see if they appear or disappear very rapidly to see if they get replaced by virtual electrons all the time.
So is this possible that real particles get replaced all the time, but we wouldn't know any better? (No way to tell from experiments.) Or is there a real effect which we can calculate if they interact like this? If they do not interact like this, what's preventing this interaction? What conservation law or laws of physics is preventing this seemingly logical, should happen interaction?
P.S. take note that I am not referring the the middle part of Feymann diagram when I said virtual particles, but specifically pair production virtual particles which interacts with a real one.
