Of course not! Everyone should have a fair chance on competitiveness, given their station and position within the community (a convicted Necromancer should perhaps not have the same rights of trade as others, for example). However, I would strongly oppose anything which forced traders to sell or purchase at set rates (as I have heard of in other lands), or be unable to compete with one another based on rules of a Guild, or other such restrictions on their normal mercantile endeavors.
As an example: Should Master Fargal propose a place where it is -expected- that items are turned in at cost, and -expected- that people may purchase from that Guild (and *only* that Guild) at a specific multiple of cost, I would be strongly against the idea. If instead, Master Fargal is merely advertising a new operation that is intended to compete fairly against other existing mercantile operations in the area, no problem. Or if Master Fargal is looking at coordinating buying and selling patterns across merchants - perhaps this Guild buys unneeded items at cost, and will resell them at cost to other Merchants in the Guild who have standing "buy" orders against specific items that come in - then I would be interested in finding out more. Either way, more detail is needed - that is why I asked for such.
