@Indirik- And suppose that the realm did decide to ban him- all right, let him face the consequences. Sucks for him. But at least he brought it upon himself. The consequences he may or may not face isnt an argument for the cap.
@fodder- eeps, noticed a typo. I mean discourage, not encourage. In BM now, if you produce a surplus, and your viable trading partners are not on good terms with you, you can either hoard it and let it rot (better than letting it get into their stinking hands!), or you can jack up your rates to 50 gold per 100. The fact that people are still buying at 50 gold, means it is still worth more to them. That is why I feel the cap should be increased a bit, to allow the buyer and seller to gauge the price the other is willing to sell/buy at.
