> Electron is always a point, no matter what wave function it has. Therefore, from this perspective space is all empty.

That depends on what interpretation you're going with. Even with that caveat, I'd be surprised if most physicists would agree with that statement. Electrons are in fact described by the wave function. It's not that the wave function tells us where the electron is, but that the best way of describing the reality of the electron is through its wave function. How and why measurements seem to cause that wave function to collapse to a definite location is different depending on your interpretation of QM.
