Quick, bug-related ways to get cash can have serious repercussions.
Say for example, Player A posts a bounty on Player B and all his friends/colleagues. A bounty can seriously affect someone - Player B and his buddies find themselves running or having to log off frequently if enough people are after them (usually because there is a large reward).
Player A needs to spend a lot of time trading simply to pay for the bounties. However if Player A can access a lot of money very quickly (I'm talking in the tens or even hundred of millions here) then A could effectively drive a complete faction into a state of perpetual victimhood without lifting a finger.
I think this aspect of the game shouldn't be under-estimated. A few of us have a lot of responsibilities outside this hobby, so every moment in game can be precious. I loathe trading, but who doesn't.
