Our best understanding of the universe tells us there are no such things as point particles. There are quantum fields with localized excitations that we refer to as particles. A theory of quantum gravity won't eliminate the fact that electrons act that way when actually observed (they have a "smeared out" effect in a region near but outside of the nucleus that has physical dimensions greater than zero).
