I think i would grab armfuls of it on the basis that money is not real anyway. I would suggest to anyone who wanted it back that it was FIAT money anyway and there was no way enough gold or other Government backed commodities to give it any intrinsic value and so giving it to them would amount to me defrauding them or at least being an accessory to them giving it back out to people and pretending it was worth anything. I may have another theory when using it to pay bills and things though.
