My question about something being fiat currency wasn't directed at the gold example, but instead at whether you thought "head tax coins" in my hypothetical scenerio were fiat currency. The only reason I brought the gold example into this hypothetical scenario was to convince you that my "said organization" was a government that clearly imposes monopolies by force. The government clearly uses force in the gold example, but the same government would not use any force for the head tax coins. Basically, I want to challenge your definition of fiat currency being a currency imposed by force by bringing up a counter example, the government issued and completely voluntary "head tax coins" that have no commodity value, no representative value, and the only value would be derived from them being able to be used to pay a voluntary tax to the government. Nobody would be forced to pay the head tax, use the head tax coins, or accept the head tax coins. Is the hypothetical scenario of head tax coins an example of a fiat currency that is an exception to your requirement of fiat currencies needing to be imposed by force or are these head tax coins viewed as something else by definition like merely government issued tokens that people happened to use as currency? I'm just trying to understand what makes something a fiat currency, and I am not convinced force is theoretically required 100% of the time by definition.
