So, hey. My community needs an outside opinion on something.
First things first, we exist on the Rim. Before you make any assumptions, no that does not make us anarchists. We simply happened to be in the middle of a project when the Fall hit and have thereafter found it convenient to remain far, far away from the sapient rights violations and unethical business practices found in the Inner System. Unfortunately this means most of our neighbors are anarchists, which makes it very difficult to trade goods and services outside of a bizarre barter system which seems to use popularity as a store of value.
While we've been able to operate in this manner for quite a while now, it's been over a decade and there are those among us (myself included) who feel it's time to help our neighbors readjust to a proper monetary system. As such we're attempting to once again follow the steps that brought us money in the first place.
The first and most obvious step is to introduce a universally desirable good into the system. Once such a good is available, anyone will be able to trade their own goods or services directly for it and then use it to obtain goods or services they themselves desire, cutting out the arduous process which comes of seeking to exchange favors with someone. Since we and the habitat in question both possess nanomanufacturing technologies, the only universally desirable goods are effectively raw materials and energy to be used in the manufacturing process. We figure that in time we'll start to mint these into the shape of a coin, then give out certificates for a given number of coins and within maybe another decade even the most hardened anarchist should once again be familiar with the concept of fiat money.
Which brings me to my original point: is there something else anarchists like that could serve as a medium of exchange? Preferably something that doesn't suffer from being made round and kind of flat? Expert opinions welcome.
