Efiniti,
I'm not sure I understand your idea. Could you expain in a little more detail?
If we abolish the Fed then we'll be left with the banks issuing their own currency for their own commodities. Of course these currencies are arbitrary numbers that are assigned a value relative to the amount of a commodity (like $1 of a BankA Note could be worth .03 grams of gold).
The problem I see is that let's say we get two or three reputable big banks issuing their own currencies through silver, gold, etc. Obviously the value of gold per gram is not equal to the value of silver per gram so the value between currencies representing those commodities will most likely be different as well.
So if we have these two or three reputable banks issuing their own currency then businesses would be accepting two or three different currencies. They would have to price their goods or services on two or three different values and constantly keep up with the fluctuations in value of each of these currencies to efficiently price their goods. The level of complexity would increase proportional to the amount of banks issuing their own currency.
My thought is that instead of abolishing the dollar we can make the dollar a unit of currency that any bank can adhere to. So no matter how many banks or how many different currencies we get the currency will stay the same on the consumer level. The dollar could just be a standard of currency.
BankA, BankB, and BankC can all issue currency in denominations of the dollar (the standard $1, $5, $10, etc) so any business can accept any currency and not be worried about doing the math. They only have to consider if they trust the stability of a currency issued by a bank. $1 of a BankA note would just be redeemable worth a certain amount of gold equal to $1 of a BankB note worth a certain amount of silver equal to $1 of a BankC note worth a certain amount of another commodity. The value of the currency stays the same while the commodity and amount of that commodity per currency differs.
Now the only problem that exists is who gets to decide what commodity the dollar unit gets pegged to initially? It would probably be through a currency board that could even be chartered by the government. It doesn't really matter. Only the free market decides the true value of commodities and if the government is assigned this task and fails (its quite hard to fail at just assigning the dollar to something) then the worst that can happen is still having decentralized money.
I was reading up about decentralizing money online and come across a link speaking of some of Hayek's proposals. This is idea came to me. It probably is one of Hayek's proposals.
But like I said I hadn't really discussed this with anyone so there could be some problems with this system.
