Title: Transition time for items among nobles
Summary: Impose a period of time before the nobles can buy/sell their items from/to other nobles.
Details: I think it's no secret how items can be bought and sold between nobles of the same realm or even of different realms to transfer gold deliberately. As the system is being made with gold and not bonds, there's two changes to avoid such trick: a certain time to transfer, or do it with bonds instead of gold.
Benefits: Implicit. Instead of trusting that we are all infallible, create methods to ensure that we are indeed infallible. Game mechanics instead of simple trust.
Possible Downsides/Exploits: I failed to see one, since the current system is already "failed" in this point of view.
