Two tools: One, commoditize your complements. The complement of satellites is rockets, make rockets cheaper and you simplify the process of getting to space.

Two tools: One, commoditize your complements. The complement of satellites is rockets, make rockets cheaper and you simplify the process of getting to space. Second, build towards economies of scale. A one-off is going to be ludicrously expensive, even the Apollo program saved money by reusing technology from military missiles. SpaceX has built more than a hundred rockets and launched more than a thousand satellites. Asteroid barons launching megatons to orbit would certainly make launching a 6.5 ton payload a non-issue. The complexity in the smartphone in my pocket boggles the imagination, I bought it for $200 but if it was a one off you'd have to be Bruce Wayne to afford it.
