Unfortunately the whole “industrial scale creation of fuel and materials” on the moon is a fantasy. Not that it is impossible, but that it isn’t being developed now. We need have at-scale test articles begin developed today. We need to see a solar powered electrolysis plant in operation today that can generate fuel in the same way it will be done on the moon. Lab experiments don’t cut it, engineering needs to be done. If NASA were serious about it they would be building this infrastructure right now. I think that the current funding scheme limits the agency’s ability to confidently invest beyond just the minimal next step to get to the moon.
