Have you ever noticed that sometimes your automated escorts or frigates, escorts and protects private ships or bases? Why is that?? Logically those traders would buy defensive ships and hire pilots, no? Or even your obsolete ships could be transferred to the private sector, at a price ofc.
Now that the private sector is armed, then there should be the possibility of privateer-ing! yar yar yarg! Send out your "innocent" private militia against your enemies, if they strike back then they are the bad guys! Why do they kill civilians? Because they shot first!

Also what happened to the "strength in number" doctrine? All I see is lone traders wandering the galaxy for the best financial opportunity...
The private sector represents the traders and private ventures of your population, they should be able to order the construction of their own trading bases and their own mining/gas facility. I am sure a wealthy space capitalist would build a planetary space port if he sees enough cash potential. Now this brings up the possibility of property seizure, the takeover of private property like a space port from the state and theres the potential to give compensations or not!
Another thing very essential to the depiction of galactic trading is the inclusion of space smugglers! They are the ones who keep the trade lines open between enemy empires, but they only make profit to the private trading consortium. AND they are the ones who supply the pirate bases! (They should appear as independent traders for game purposes.) You could try to hunt them but then you get bad rep for being repressive on free trade.
Well there goes my thoughts for ya. Take it and use it as you like!
