How would you be able to tell what the balance on the stick is without power? How would you be able to calculate the current value in fiat, if you had power but no internet? For that matter, how could you verify that someone hadn't transferred the balance in a transaction that didn't exist in your (now offline) ledger (if they had internet and you didn't)? At some point, if you're being practical rather than ideological, isnt cash the clear winner in these situations? YMMV if your currency isn't as stable as USD though
