Well no I dont think paper money or credit cards will be any good but I also dont see how gold will help. i.e. if you need some help from me and you offer me gold to pay for my services what good is that to me, it cant put food on my table, it cant provide warmth or shelter for my family unless there are others willing to trade my gold for their services but thats a gamble of my time and energy which in a situation like that I will most likely be trying to preserve.
