From my opinion xenos should have different approach at the traders incoming to liberty and liberty traders exporting goods out.
Although its both bad and I hope that xenos get their way, the way of the honest hands earning the money trough sweat and hard work instead of capitalist power hungry mongrels taking over liberty and destroying the fragments of ol' glorious self, the xenos should react differently at foreigners and homeboys.
I'ld say that foreign trader should get pretty much mashed up, his cargo destroyed or kidnapped and his sorry butt sent home with a big message spraypainted over whats left of his hull "AND STAY THERE"
The homeboys should be treated as homeboys who did something wrong. Drop the cargo, and go back to your mother son, I suggest you take a job at plantation or even get your own and realize some things before you sit in the trader again.
As for the LSF, well, thats kinda tricky, they're patriots as well, and they are protecting homes as well, but damnit they're on the wrong side and the limit is drawn at "hoping the poor boy will eject on time".
Basically, things would go smoother if a traders need to get an affiliation and id as well.
Because people would know who to pirate when, what to pirate and what to let go, what to fine and who to kill on sight.
And ofcourse, it would lead to the nice good sweet privateer ID's too and indenpendent traders would be left with less, or no rights at all.
