Therefore, while it is absolutely necessary that a money originate as a commodity with direct uses, it is not absolutely necessary that the direct uses continue after the money has been established.
Here is a paraphrased summary of the excerpts above:
point #1) It is absolutely necessary that a money originate as a commodity with direct uses.
point #2) If an established money were to stop being used as a commodity, it would not necessarily lose its character as a money.
I believe point #1 is a big obstacle to bitcoins because I don't see any direct commodity uses for bitcoins, and I don't consider the many monetary and exchange properties of bitcoins to be direct commodity uses. This is why I like thinking of ways to back bitcoins with something that has a direct use as a commodity.
Point #2 seems to leave open the possibility of something like bitcoins getting around point #1, establishing itself as money, and then maintaining its character as money with no need to ever have a use as a commodity. However, I believe the underlying commodity use of a money is an essential ingredient that interacts with its monetary and exchange properties to make it more desirable to use it as a money than as a commodity.
There doesn't need to be a loophole around #1, because Bitcoin
does have a use value. That use value is derived from the software that forms the client as well as the network. Software represents organized work toward a goal, namely to create a logic machine that performs a desired function. In the case of Bitcoin, that function is to transfer
value (not wealth, which is different) over vast distances at unmatched speed and for a very low cost. The kicker for bitcoin (the currency itself) is that bitcoins are required for this function, for no existing form of currency can cooperate with the Bitcoin client to this end. Adding confusion is the fact that, due to the nature of a decentralized currency, there can be no form of backing or peg. So the relative value of bitcoins verses existing currencies must float. Thus the chicken and egg problem then becomes, how does one get an initial
relative value for bitcoins? It happens to be that said initial value was established when an early adopter, wishing to advance the currency, chose to offer some of his vast holdings in return for a pizza. He offered 10K BTC, and someone else decided that it was worth that
to him. All of point #2 flows from this singular event, but the
use value that those two traders saw in bitcoin wasn't in the pizza, but in the functions that the currency and the client together could perform. I.E. to move
value across limitless distance. It is this function that no other prior currency on Earth, fiat or otherwise, could perform in an economicly competitive manner.
