Ah! That makes sense. But surely there is a point at which this economics becomes true for terrestrial datacenters too (in fact I saw some glimpses of that 10+ years ago, demonstrations of shipping-container-sized self-contained units that you just plug in power, and replace the whole container when it gets degraded). If they're not doing that today for terrestrial datacenters, then it probably doesn't make economic sense yet to do it in space either.
