We still have our monetary system; use it while it lasts. Think about how 'wealth' may be redefined in the very near future, and use the resources at hand to prepare yourself. I'd say that the #1 "must have" for me is a portable ceramic/charcoal water filter... I have my search & rescue pack all ready to go as usual, and I've got a small stockpile of high-energy/high-nutrient foods just in case I have to move fast. Beyond that... I'm going to wait for something definitive to happen. No sense in wasting my energies by investing myself in the wrong course of action.
Life as we know it is gong to change. Enjoy this paradigm while it lasts!
