Just FYI GTO sats' launch costs on the higher end of that range when buying from SpaceX (if not higher), while Starlink launches had internal cost 30M BEFORE current very high launch rate, which will bring costs down more.
So not quite an order of magnitude, but 5 times difference in launch costs should already be achievable.
And Starship will bring another 5-10 times cost reduction when measured per kg, even when you assume pessimistic mass margins and costs / launch rates.
