It's not backed by nothing. That's empirically, objectively false. You just don't like what's backed by. In another comment of yours,
"In my world, goods and services I purchase are the final goods, not the money I need to purchase them."
This is also objectively wrong. Sorry, the dollar is backed by the US government and I'm afraid those things are derived, not fundamental.
You are mistaking what you want to be for what actually is. And because of money's recursive nature, regardless of what you think about that, the fact that a dollar can be used to pay off Uncle Sam means it's usable to pay for a loaf of bread, too.
Furthermore, it doesn't matter what you base a currency on, it will always work this way. Base it on something like gold and the currency will still have higher order effects that aren't directly connected to gold. That's the entire purpose of money, to reduce the problem of trade to a single universal currency and thereby enable an economy to develop, instead of being stuck on barter. Barter may be concrete, but that's just about the only positive thing going for it.
(Even a barter-based economy will still prove vulnerable to bubbles and all the other problems of a money-based economy, it just won't also generate enough wealth to survive such things. Some things like economic cycles are fundamental to economies themselves and can be seen in economies where Man has no participation at all. Ecology can be seen as a degenerate case of Economics with no intelligent participation.)
