There is absolutely nothing precluding a metals centric ISRU implementation on the Moon that would have an immediate upstream effect on the entire architecture for lunar/Mars exploration.

In all of the discussions about heavy lift, I have never been able to find anyone who can list more than a few payloads that require a heavy lifter. These are things such as a habitats, pressurized rovers, power systems, and humans.
