Does not being able to tax food take away from the idea that food is the lord's own produce? What purpose does food serve in that case other than a mildly different form of less useful gold?
Rather than try to tax for food, has the idea of simply using the royal treasury to buy food (which the Banker can do) been considered?
Is not the gold produced by the Lords region ALSO his own produce? Where does the idea that the Lord owns his food come from. When you look at it some realms impose this idea to offset the fact that Lords of rural regions get poor gold incomes. It is not an inherent tenant of the game just one more arbitrary aspect of realm culture, much like realms that insist all food is owned by the realm.
However historically tax on food was extremely common.
And yes, the original idea allowed the banker to buy and sell from the royal Granary as well as impose a tax.
