Good idea and all that but it again comes down to the fact that old Kusari was isolationist, see that doesn't work for a house that well because of economical reasons, that coupled with the fact of state-backed criminals pirating down any and all foreign transports is a HUGE set back to the economy.
Samura -no matter how large of a corporation it is- is not sufficient to back the economy of an entire house with it's vessels alone and most of the gas is owned by the GMG, not the state.
Now take all that, and add in that Kusari's military and economy has been crippled completely, so by continuing to out foreign entities their economy won't be stabilizing anytime soon, of course, Gallia -has- forced trade with Kusari so that's a bit of a saving side, but really, isolating the house is a completely wrong move.
It all comes down to the devs caring about that side of sense of course.
