> It’s not the new paradigm which requires higher volumes and lower margins, it’s SpaceX’s business model which requires it (or, I suppose, expects it)

I know it's not a perfect analogy but cheap and predictable global shipping enabled business models which were not possible before.

Maybe cheap and predictable access to space will do the same.
