A modest clandestine bunker close to but not directly in a population centre might fare a lot better than these pinatas. Especially if everyone else has run off to raid the Theil compound.

I think if i was this rich i wouldn't just build a bunker in the middle of nowhere but invest in existing town, help them become more independent/self sufficient.

Same for wherever i lived, the more people protected from a disaster the quicker they can rebuild.
