I see where your coming from Ivan. I mean, say FL was real life. If you were a station dealer, would you rather buy goods from a ragtag trader thats probably just been on some Junker base doing a shady deal OR a Universal shipping captain in a nice suit with an official name tag that says Hello, my name is: :).
Some would say that FL is not real life. I would say that we should try and make it as realistic as possible. Soo..a ship restriction on Freelancer/Merc IDs for trading for like say, no ships over 3300 cargo or something would do the trick? Because, think about it. Youre average Freelancer doesn't go around with 100's of millions in his pocket.
One problem though. People will start to spam Junkers.
