One of the coolest things about cash money is accessibility despite a lack of comms. For most of my life, I was able to access food, beverages, etc. with coins and paper. August 2003 - The Great Blackout. Remember? Credit card terminals down, cash only at the gas station? IMPOSSIBLE now, amiright? In a crypto utopia, what happens when the lights and/or comms go out? How do you get 0.00522875816 BTC transferred to a station for a tank of gas when the Internet is toast?
