Guns would be a must have for currency in chaos. Also organs. If you could come up with a portable freezing system, you could take the organs from those killed by the currency guns, and then sell them on the chaos market to those wounded but not killed by the chaos guns. Of course you would be selling/trading the organs on the chaos market for either more ammo, or food, unless you ate the organs, in which case I think we should have some preset chaos rules of no cannibalism unless absolutely necessary.
And you'd be my bank organ, instead of freezing your parts, I'd just barely keep you alive until I need something to barter with.
Though, based on your post, I have to assume your liver will be of no use due to drug abuse.
Then there is the question of STD seeing how you most likely engage farm animals, so the rest is obviously contaminated.
Ah Hell, turns out you're probably absolutely worthless, so I'll just use you as target practice.
Start running ass hole, you got to the count of 10. 1...2....11, BANG... damn, never really could count.
