I do agree with you that GR cannot be a fully correct description of reality on a quantum level (because of this and other issues, especially many worlds). I was saying that we should take the structure of GR into account when building a unified theory, rather than just starting off with the assumption that gravity works exactly like all the other forces.
This is what the proponents of the loop approach usually stress—demand that the theory be background independent, or general covariant (I am not sure whether there is some important difference between the use of these terms).
