Indeed, there's no rule against this as is, but I'm somewhat surprised at how clear cut your stance is, Tom, given how much resistance there was to give bankers power over food by the dev team, specifically because of fear of this kind of behavior.
Because it is so easy: Does it violate an IR ? No it doesn't. Case closed.
Whether or not the underlying game mechanic could be improved is an entirely different question, and a lot less clear cut. One is a yes-no question ("did you break the speed limit?") and the other is a detailed background argument ("shouldn't the speed limit be different in this location?").
