How is the current Bitcoin system going to spell any of this out? You can see transactions in/out. You don't know what's going to supplier or which ones. You don't know what's going back to customers. You don't know anything but money in/money out. It's like looking at a banking balance sheet that has everything blacked out but the amounts. It isn't going to give you any information that isn't already public. Blacking out the numbers as well has no benefit at all.
