No, this is false. Gold and silver had innate value long before anyone "in authority" declared this to be so. In fact, central authorities eventually recognized the value of gold and silver, they didn't declare it or bring it into being.
The really remarkable event, that cements the role of modern government in economic matters, was the relatively recent unlinking of paper money from the backing of gold and/or silver. This step was taken for a number of excellent reasons, but it was predicated on the idea that the public will have faith in the stability of the economy, not on the innate representational value of paper money.
Then the USD was decoupled from everything.
Far before any of that, people actually used gold and silver coins and pieces of coins as currency.
TL;DR Gold-as-currency first used in Egypt 4,000 BCE; Egypt implements a commodity-tax somewhere between 3,500 - 20 BCE; Coinage first cited between in Lydia 700 - 550 BCE.
Could you give me an example, like I originally asked?
http://en.wikipedia.org/wiki/History_of_money#Early_usage
> It has long been assumed that metals, where available, were favored for use as proto-money over such commodities as cattle, cowry shells, or salt, because metals are at once durable, portable, and easily divisible.[45] The use of gold as proto-money has been traced back to the fourth millennium BC when the Egyptians used gold bars of a set weight as a medium of exchange,[citation needed] as had been done earlier in Mesopotamia with silver bars.[citation needed]
http://en.wikipedia.org/wiki/Lydia
> According to Herodotus, the Lydians were the first people to use gold and silver coins and the first to establish retail shops in permanent locations.[12] ...
> The dating of these first stamped coins is one of the most frequently debated topics of ancient numismatics,[14] with dates ranging from 700 BC to 550 BC, but the most common opinion is that they were minted at or near the beginning of the reign of King Alyattes (sometimes referred to incorrectly as Alyattes II), who ruled Lydia c. 610-550 BC.[15] ...
http://simple.wikipedia.org/wiki/Ancient_Egypt#Early_history
> Ancient Egypt, or the Egyptian Empire, was a society that began about 3500 BC and lasted until 20 BC when it was invaded by the Roman Empire.
> Ancient Egypt had a lot of different taxes, but there was no real money, so people paid each other with goods or work. The person who watched the tax collection was a scribe, and every tax collector in Egypt had to tell him every day how many taxes they had collected. Each person paid different taxes based on the work that they did: craftsmen paid in goods, hunters and fishermen paid with food, and every single household in the country had to pay a labour tax every year by helping with work for the country like mining or for canals. A lot of rich Egyptians paid poorer people to do this for them.
2. Does the article call the gold bars "proto-money"? Sure, but now we're just bickering over definitions. The same article says the Egyptians used gold bars as a medium of exchange, which I believe exactly fits what we've been discussing. If you define "currency" to mean something other than a "medium of exchange", then what is the distinction and how is it relevant to Bitcoin?
3. And this brings us back to the original point of contention ITT: Why do you believe a a successful currency (or successful medium of exchange) requires a centralized "standard" despite historical evidence of decentralized "commodity money"?
The "gold standard", in the US, was established by federal law in 1900, replacing bimetallism, the previous basis. Respectfully, I don't see how the use of precious metals in Ancient Egypt is relevant to the role of currency in a post-industrial world.
It appears our disagreement lies in "post-industrial". My first thought was "I don't see how the use of precious metals in Ancient Egypt is any different from the role of currency in a post-industrial world." Now, asserting our myopia leaves us nowhere. But as long as this thread is already, I'd like to dig deeper.
Given the Mt. Gox debacle, I'm assuming your line of reasoning is related to trust. E.g. "the purely electronic form of bitcoin allows it to be stolen on a scale not feasible with more tangible forms of money." But then, do banks prevent the laundering of USD electronically? Or perhaps "who will insure against theft if not the government?" But then, who insured against theft prior to Hamilton's creation of the U.S. National Bank?
But at this point, I'm fully immersed in strawman land.
Ideally, I wanted to understand your reasoning. I still haven't gotten very far. Consider that if I can't decipher why you disagree and I'm not permitted to construct hypotheticals (strawmen) as to why you disagree, that leaves me with either assuming you're automatically wrong or not thinking critically at all.
Derailment? I don't think that's fair. Until now, I've been pursuing the same question this entire thread (why you disagree with top post).
