in light of your arguments (appart from those where you don't make enough cash when only RPing traders:P) I shall adjust my opinion on that matter: I still think that its fair game to earn those 30-40 million an hour when trading alone. However, making mining more efficient (40-50m$/h - similar to the profits of the old diamond-niobium run) thus encouraging people to socialize more and get to learn the rules faster by being introduced to the community earlier, might actually be the best course of action.
Edit: Actually I lied. This was my opinion for the last one and a half years. but xoria blocked the mining lobby because he'd rather have half of sirius on the lanes silently power trading for his own amusement D:<
