I actually disagree with some of this. The poles are not the only place on the Moon that will ever be settled. And the total available permanently lit surfaces are small compared to total potential future need. So, fusion notwithstanding, you’re looking at panels, plus either a lot of wiring (so some panels are always live) or a lot of batteries.
They state it’s temporary and that NASA is looking into nuclear. This idea is for the initial founding of the base and Wall-E will be able to manage the area around the settlement.
Idk if it’s worth it to make a settlement on the idea that something better will come along and fix/replace things. Would it not be prudent to await the technology for transporting radioactice payloads? If we fail, will we be able to upkeep the moon base? Will it be worth it? (Besides the cool factor of having a moon base because that’d make the question rhetorical)
