as long as they are not gold or silver, and thus legal tender.
Gold and silver are not automatically legal tender. That is up to each State. The Constitution just limits the options for
possible legal tender to only gold and/or silver:
Yes, I know. What I was referring to there was competing currencies, and should have more specifically said: as long as they are not gold or silver, and thus
compete as legal tender. But since you are pressing me on this point I would have also defer the question of whether or not competing currencies could also be gold/silver to a Constitutional law expert.
There's no need for experts. If the architects of the Constitution had intended the Federal government to have a monopoly on legal tender, they would have written exactly that, instead of what they did write which was to leave the decision up to the States, within certain limits.
Fair enough. Then I'll imagine for now it's only States that can't coin gold and silver. Private individuals and Congress can.
So, since Federal Reserve Notes are not paper, nor even a commodity, then what exactly is your argument?
Federal Reserve Notes are not paper?

And you think paper can't be a commodity? Let's say the U.S. experiences massive hyperinflation resulting in total loss of confidence in the dollar, or more accurately Federal Reserve Notes. The many newly poor and homeless on the streets might be glad for paper to burn for warmth. You're saying a vendor wheeling stacks of FRNs down the streets in a wheelbarrow (perhaps along with matches) selling for gold rings, bracelets, etc., and the people lining up to buy a source of warmth for the night wouldn't be purchasing a paper commodity? Which universe exactly are you in?
You're right, probably not significant value, but I only claimed stable value.
Nice try.

The value wouldn't be stable either. If there was any value you can bet those with the ability to create more dollars (the govt.) would do so since they would not be restrained by the ability to honor the backing. This would mean inflation and loss of value, even if the value was small to begin with. You either have zero value, or some value. I've shown why your statement is false, unless you meant a stable value of zero?
I thought we established that only gold and silver can be legal tender?
Do me a favor and get a
paper dollar from somewhere. Look for the words "legal tender" on it and let me know if you don't find them. We established the
Constitution says only gold and silver can be legal tender.
Who says there was an attempt to maintain the value of the dollar in terms of silver?
Uh, you did? And you got it from Jefferson and Hamilton and the Coinage act of 1792:
I said the value of the U.S. dollar was
based on a certain amount of silver. I did NOT say there was an attempt to
maintain that value. Your problem appears to be failure to account for fine distinction. The Constitution gives Congress the power to coin money and regulate the value thereof. If Congress instructs the U.S. Mint to create 1 dollar coins consisting of 1 ounce of silver then Congress is legally exercising its Constitutional authority. This says nothing of any "attempt" to maintain the value for a dollar. The legal instruction to the Mint is not an "attempt", it's an instruction.
Now if people in the marketplace want to price their goods in dollars and accept those 1 ounce silver coins Congress had minted that's their business. People are NOT forced to use those coins if they feel they don't provide enough value. People are ONLY required to accept them for settlement of debt owed them if they are declared legal tender.
So I hope you can see, as I said above, it's only
people that can ultimately decide the value of something. Foreign coins consisting of 2 ounces of silver might be the preferred choice of the marketplace to use as dollars, for example. And in this case Congress still hasn't failed at any attempt. They can go on defining 1 dollar as 1 ounce of silver. Some in the marketplace will recognize that value simply because it's the legal national currency.
But as I've pointed out the people and the marketplace have never rejected that definition of a dollar. Indeed, people WISH they could get as much silver per dollar as the original definition stipulates. So where is the failure?
Indeed, what we are missing IS an attempt to maintain the value of a dollar in terms of silver. IF this WAS the attempt we would never have stopped paying out silver/gold.
We may have had failure in political decisions in history, yes, but we haven't had failure for trying to define the ratio of silver to 1 dollar.
The flaw of fiat currency is that it attempts to assign value where there might otherwise be none.
Sounds like denomination to me.
I'm sorry what it
sounds like to you. Let me tell you what each
is.
Fiat is a decree. So fiat money is money that becomes so by decree. This means if the government wants to declare that sticks are money, then sticks will then be money by decree. The problem, which should be obvious, is that simply declaring that something (like sticks) has a certain value, or any value at all, is inherently flawed. Why? Because the assigned value has to be accepted by people who have free will and probably other ideas about what is valuable to them.
Denomination is a value or size (as of money), or the act of denominating.
