Right? So if that's the case why would putting them in Space, far less accessible in every conceivable way, with numerous additional expenses and engineering constraints, be cheaper?
Maybe there's a concentration in VA because there's a set of deals/procedures in place with infra providers there that make it easy to scale up, similar to how DE has well developed corporate infrastructure, so everyone incorporates there. But that stops when the area hits its limit in power provision (which seems to be happening right now). In which case, being able to do this yourself end to end by putting this stuff in space with your own power generation makes it the ultimate scale-up opportunity - no real limits on space or power availability, so once you get that method down, you can mass-scale and get great economies of scale. Maintenance isn't a thing, these will be disposable.
I think that's it, money's not the limiting factor if they can pitch this successfully, which I think they will. They want massive scale without the constraints you hit when doing it on earth. I think he's aiming for scale that we haven't seen in DCs on earth.
