alt Hacker News> Fiat currency isn't just a matter of belief or stories
... Then how do we, as a society, determine how much a dollar is worth?! We do use force to enforce the stories we tell about fiat. But 'believe this story about how much a dollar will buy you and how much you owe, or else we will send thugs to your house' isn't disproving the point at all.
Determinations of worth are irrelevant. If the government says you have to pay $1000 in taxes then you have to come up with $1000, regardless of any stories or beliefs.
