Yeah, it's such an interesting idea that there's just some guys who know how the tech works, but they're not weird about it

The main conflict with them is that they've settled into a comfortable place, they've never had to deal with a harder wasteland, so they don't really believe that the player needs any of their tech or expertise

They're not trying to keep people out, they think they can just offer safety and stability to everyone and it'll be fine

Not realizing that there are forces out there that might take advantage or even just try to take it away from them anyway
