I think that if companies want to scale up rocket launches (and let's disregard the cost / environmental impact / etc for now), they also need to scale up launch sites, at the moment they seem like single points of failure.

I have only armchair amateur half a world away knowledge of this, but I want to believe all they need is an exhaust diffuser thingy and refueling capabilities; the former can probably be built cheap enough anywhere, the latter can be made portable.

(of course then you also have the challenge of assembling and loading a rocket, lmao. But a hub-and-spokes setup with VAB(s) and launch sites spread out around it like an airport could work. Bonus evil villain points if the launch sites are underground to contain explosions in case of failure.
