>We'll have Gateway in NRHO but that's one of the few places it's actually practical.
It's Orion that's impractical

Mostly just Orion

Ultrasafe is actually shit, not just misleading. From their NIAC bid in 2021:
>USNC-Tech is proposing a compact 20 kWe, 500 kg dry mass, radioisotope-electric-propulsion spacecraft design powered by a novel Chargeable Atomic Battery (CAB) that is capable of ∆Vs on the order of 100 km/s with a power system specific mass of 5-8 kg/kWe.
So the beginning of life specific power that is worse already demonstrated solar panels. The battery has a shelf-life of just months despite that a high energy burn with electric propulsion could take years. Realistically it would end up expended as recharging would require them bringing it back to Earth.

Looks like NRHO the best orbit Orion can access and still have fuel reserve. Overall LLO seems ideal for a depot or the staging point for a lander, the delta-v required for station keeping really isn't that bad.
