>"in the modern world, if it exists and is desired, people will agree on a dollar value" - applies only to currencies where 'Trust' is a given. I don't think that's true. If a currency is untrusted, people will assign a lower dollar value to it, but it's still going to have a dollar value. >Or, it should be a limited domain (e.g. gaming currencies). I'm confused. Are you saying that gaming currencies don't have a dollar value?
