I don't see any abuses that could be made but I am sure someone can think of one but price should be determined on supply and demand not some dumb cap. Tom wants use to trade food but at the cap it is really not worth my while to trade any food. Everyone always talks about they have plenty of gold to buy food with but no one to sell to them. I know the reason for me is that a max of 50 gold per a 100 units is not worth it for me. In times like winter and droughts food prices should sky rocket because no one has any but with a cap their will always be a predetermined max price.
If I as a lord want to sell food at 300 gold for a 100 units then I should be allowed. Their will always be ways people find to abuses the system so trying to put a dumb cap on how much you can sell food for only causes people to not sell food.
