Real cash still depends on gold. But now we a have a new player called bitcoins that depends not only on gold but also on cash, so... gold -> cash -> bitcoins.
Without gold and\or cash bitcoins are simply useless. But not only, even with gold and cash, if there is a power grid black-out your bitcoin wallet or brainwallet is useless. Remember Katrina or sandy?
