There is nothing that Indirik, Anaris, or Vellos has said in this thread that I disagree with. How often can anyone make that claim?
Recognizing the value (and intent) that food can provide in creating tension and redistributing wealth and power down the lower rungs of BM society, it wouldn't be doing any harm to make food as close to "set it and forget it" as possible. Things like automatic sell offers, where a region's granaries are opened to the duchy/realm/all comers at X price until Y threshold, and a button that allows the banker to manage the affairs at the risk of reduced profits for the regional liege, would go a long, long way to getting people out of a perpetually conservative mindset that stifles fun, creativity, and action. It's BattleMaster, after all. Not EurozoneBudgetMaster.
