It's also increasing at a controlled rate. To make your analogy more complete, it'd be like all the diggers are aware of each other and whether they've found a USD or not. If too many are being found at once, everyone switches to using their hands. If still too many are found, everyone uses their tongues. If too few are being found, shovels are allowed. If still too few are being found, backhoes are allowed.
