If there's no goal of making an eventually long-term self-sustaining colony, it isn't clear what goals there are here that are a reasonable use of resources on this scale.
Long term settlement, yes. Self-sustaining, no. There's no realistic prospect for a Mars settlement becoming self-sustaining either. Either one will require ongoing support from Earth for the foreseeable future.
Here are some valid goals for a settlement on the moon. It can serve as a gateway for missions to more distant places. Once you're out of the Earth's gravity well, a lot of things become easier. It can mine resources from the moon that will be useful for anything we want to build in space (titanium, aluminum, etc.). Construction in space will become a lot more practical if you don't have to launch all your raw materials from Earth. It can do science. The far side of the moon is a great place for telescopes. It can perform a lot of the same functions we currently do with satelites (observation, communication), but much easier to maintain and service.
It also can be used as a launchpad for weapons that attack anywhere on Earth. Yeah, not all the potential uses are good ones. I wonder how much of the geopolitical urgency is driven by that?
