But, of course, that doesn't answer the question as to why rations and ammo are "unimportant" bean counting, but hit points and gold pieces are not. If you only care about what is "dramatically appropriate" on the basis of your "story", then why should you care exactly how much money the PCs have available to them? If you want the PCs to be able to buy something, they simply have the money. Likewise, why bother bean-counting hit points? If you want them to drop, they drop. If it isn't "dramatically appropriate" they do not. Likewise, rather than roll damage, the DM (or players) simply decide how long a fight should last. Indeed, if your primary concern is the "dramatically appropriate" narrative you are creating, why bother rolling dice or having game rules at all? Why is any of the bean-counting important to any degree at all?
