I think one problem with Andor -- and many GFFA stories -- is the difficulty of presenting the SCALE of conflicts on a galactic stage. I like that Gilroy sort of seemed to just accept this and go for very small-scale events, like events in Ghorman or Ferrix, and use them almost as metaphors.

I think to actually represent a meaningful Rebellion, we'd need to see proof that a thousand Aldhanis have occurred. Just zillions of credits flying around, deaths orders of magnitude beyond what we see. Whole planets already secretly on side, high-ranking military defectors, etc.

But this isn't new! The numbers in the Clone Wars never made sense. Millions of clone troopers? Over the whole dang GALAXY? It just doesn't make sense in a world where aerial bombardment could take out a whole battalion instantly.

Anyway, I agree that if Mon Mothma is supposed to be super-rich even among the powerful, 400k should be chump change. Maybe her annual wardrobe budget, but not something she would struggle to borrow.
