Dynamic network

Since in 6G there will inevitably be some base stations that cannot be statically fixed but are mobile, why not design the entire routing logic based on dynamic base stations directly? 

About 20 years ago, some people called for spectrum reorganization to avoid problems such as interference with avionics by ground mobile communication devices with different communication protocol systems on the aircrafts. 

Since 6G will be to integrate terrestrial and non-terrestrial base stations to be the 3D network,  why not take this opportunity to reclaim and reorganize the entire spectrum for overall re-planning?
