First of all freelancers are not unlawfull, so they have no problem with pirates docking at their bases. You love to pirate but don't like using freeports ? okay, try these systems :
Coronado: Gives you access to the Taus, Bretonis, Liberty
Koeln: Gives you access to the Omegas, Bretonia (only a couple of systems away), Rheinland
Sigam 13 : Gives you access to Rheinalnd , Sigams (obviously), Kusari, Omicrons
You get the picture.
Pirates are in fact pretty much freelancers and are welcome to dock on freelancer bases. Furthermore all unlawfulls as far as I know, are welcome to dock at freelancer bases. So pirates and other unlawfulls don't really need a separate system for them to meet?!!?!
Like someone already mentioned, there are a lot of systems already, we don't need more. We barely use the ones existing now.
Edit: also let's not make this an indies VS officials thing, because , believe it or not all members of any official faction, also have indie chars, like all of them. So no one wants to hurt indies here.
