Of all the different categories of money, and there are at least 5, money in motion is by far the most important. Lose control of that and all commerce will immediately stop. If it is not restarted quickly,society as we know it will either replace it with a different medium of exchange or collapse almost immediately. Then bullets and force will become the new medium of exchange.
Interestingly, guns & ammo corresponds rather nicely to cash. .22LR is about the same size & value as pocket change ($0.02-$0.25), 9mm & 5.56 & .308 for small bills ($0.50-$2.50), high-power .338 & .50 for larger ($5-$20), magazines ($10-$100), handguns & small rifles ($100-$1000), rifles ($300-$3000).
Thanks For THAT!
