"RIGHT 1) Official Factions are free to restrict or not restrict access to their owned systems and tax players who enter owned system. However, properly Tagged and ID'd independent players may enter Guard/Owned systems, and cannot be taxed. Access to systems that surround owned system must not be restricted unless there's a war with another faction."
Tau-44 is the Guard system of the Colonial Republic, therefore 'properly ID'd and IFF'd' players would need to wear the flag of the Colonial Remnant.
There are no Colonial independent players and the IMG are also not the Colonial Remnant.
The Colonial Remnant may use every force they deem necessary to guard this system from every trespasser.
Groups that want to purchase a Zephyr class Carrier might ask for permission via the appropriate communication channels.
I hope that clears that now.
