Well, that's why I added the line "pure money". Fiat is anything but pure.
So by "pure money" do you mean money as an IOU for work done but not paid for?
I most likely mean commodity money. Something that has evolved into money through a consensus.
I think Bitcoin fits the bill. Although the way I see it, it was created to have properties that would make it a suitable commodity money, although it never was simply a commodity (some might say it is only a commodity). So the evolution with Bitcoin isn't a commodity becoming money, but being accepted as commodity money from the start. Strange, but it seems to be working fairly well.
Money is certainly special.
Bitcoins, being a hash and unique commodity, can be accepted as a balance of trade, as can money or any other good depending on what the trader wants, and are protected as long as the hashing network remains uncompromised. It might be tempting to consider money a commodity due to it's acceptance and demand, but strictly speaking, it's not.
Either can represent different things to different people. For some they are food, for some they are luxuries, and for others they are penis lengths. Bitcoins are like money in that they are inherently in-consumable, but they are unlike money in that they cannot be easily duplicated. If you believe money to be a commodity, then I believe you might misunderstand money. I believe a more accurate way to consider money, is as your priority of access to the market of commodities. Anyone with the power to create money (banks, credit companies, govts) can put themselves in front of the line for resources, at whim.
Believing money to be a commodity, is what the issuers need the masses to believe, for them (the banks/govt/creditors) to get the most benefit out of it themselves.
