I would say that I am not against players trading urplasma for resources, but it must be regulated. Why can I not ask for someone to give me 10 billion spice in trade for 10,000 pig iron? Well - there are rules that control the trade! (And common sense - only an idiot or a cheat would accept that trade!)
So trading urplasma for resources is clearly a good strategy, but surely there must be rules!
Do I have suggestions for what the rules should be? Sorry - not yet. I will think about it first.
