What do you think is the biggest reason for ship transfer costing real money? My thought it's because different ships got different economies and they try to limit it because of that.
With only ship 1 and 2 being available on CBT and being crowded the times i played, i can see how it could be an issue to be able to play friends. Me (and probably many others) have a few friends that don't care about stuff like beta and would rather join when the game get released. Add to that all the PC players who are patiently waiting for OBT who most likely would like to join their communities like reddit and discord.
Personally i wouldn't mind starting over, as long i could take my beta rewards with me.
