Resellers don't hurt economies where reources are unlimited. That's all just in your heads. If one guy decides to buy all 'uber hat of dragonslaying' and then list them all for 1000 plat, the next guy just goes out, kill the mob that drops 'uber hat of dragonslaying' and lists it either at 700 plat, or whatever he feels he wants for it.

This idea that suddenly having easy trade fucks up the entire world, and floods the market, and does all this terrible stuff is really just such bull. It just makes trade easier.
