It really only just fully sank in....
Even after Earth joining the Federation again, the mobile starbase was still used as HQ, and as we see in the finale, years later is even expanded with more stations and still in space.
And it makes sense. For a huge coalition like the Federation, not having a HQ on a member world but rather in space seems more logical. Now ofcourse, for filming reasons it was easier to use established buildings that looked futuristic, but in-universe, I wonder why a space dwelling facility was never considered during the 23rd and 24th century.
