Every greenback may be registered. But physical currency is only a small amount of the actual circulating money supply. Due to fractional reserve banking, banks lend money they don't have. Banks are only required to have 10% of the money they loan on reserve.

You loan currency to a bank in the form of deposits, they keep some of that on premises due to the reserve requirement and loan out the rest to their other customers. In exchange for letting the bank use your money, you get insurance and a tiny interest payment. Other than it being too young and inconsequential for people to bother, what property does bitcoin have that works against this scheme? Banks have worked this way since long before modern fiat currencies were developed, and they’ve always increased the money supply without minting new coinage. Whether it’s gold bullion, federal reserve notes, or bitcoin keys in their vaults doesn’t seem to make much difference.

  Bitcoin is much like cash in that you can choose to opt out of making your money available for fractional reserve. Why with cash many don't do that, beats me. According to Keynes, people should withdraw their cash when there is no interest to be gained ("liquidity trap"). In practice, people don't, and that makes Bitcoiners crazy: good marketing makes (especially badly informed) people act uneconomically, since they think they are saving, while they are actually investing in an indifferent manner. Other important aspects of Bitcoin are, that it makes the money supply transparent, and everybody can validate transactions. This is not as simple with cash or gold.

    > Why with cash many don't do that, beats me. The banks provide a service that has some intrinsic value: They protect your cash better than you can, and store it in a place that is physically separate from your home. Home thefts occur with a higher frequency than bank thefts, and someone who's known to keep large quantities of cash in there home becomes a bigger target. If your money is stored in a bank, you're more exposed to a banking system collapse but insured against ordinary theivery. If your home is destroyed, then your money is still safe; if your bank goes bust you still have your home (or at least the things inside it).

      Keeping cash does not mean one has to keep it at home. You can actually leave it in a safe at the bank and just use the bank as a warehouse. In this case you have to pay a small fee, but you decrease the amount of cash that can be used for loans, and thus make loans more expensive, leading to better rates for lenders in the future. (At least this is my understanding at the moment - still getting into the topic, so please excuse if I am oversimplifiying.)
