According to the San Diego Union-Tribune, Republicans and Democrats alike embraced legislation last Friday that would make California IOUs legal tender for all taxes, fees and other payments owed to the state.

Effectively, California is using its IOUs to create a currency. If this bill passes it would allow California to deficit spend just like the Federal Government and with the IOU's acceptable as payment of state taxes, it instantly imparts value to them (see here and here). In effect, what you have is a state of the union creating a sovereign currency right under the noses of Treasury, Fed. They are stumbling their way into it, and as they do so, some of the true nature of contemporary money is being revealed. It will be viewed as a stop gap measure at first, and then could very well become entrenched as states realize they have a way to escape balanced budget requirements.

Contrary to most conventional economic thought, whereby people think we pay taxes to create revenue, in fact, it works the other way around under a fiat currency system. The government doesn't need money to spend, but in fact uses tax to manipulate aggregate demand, not raise funds to "pay" for government. The tax is what gives the currency its value insofar as taxes function to create the demand for federal expenditures of fiat money, not to raise revenue per se. Value has been given to the money by requiring it to be used to fulfill a tax obligation, but the money is already in existence, not "created" by the revenue.
