So basically your advise is to not bother trading during Beta. How are its mechanisms to be tested if no one is actually doing it?And when the game launches, and the law enforcement systems are in place, and it actually matters what you do and where you do it, THEN you can go and be a trader.
There are many things being tested here, or at least attempted. Combat, travel, trade etc. However the only thing being tested by many traders at the moment is their patience. Someone in a Hauler is no match, or threat, to almost anyone but that doesn't stop them getting killed due to bored pilots who probably can't handle anything more than simple traders who aren't even expecting combat.
No doubt someone will come along to defend their position to engage in PvP, as would I, but there are better places to do this and with better competition.
But then, competition is not the goal here is it....
