That analogy fails badly. It could be said of any fiat currency. Take some Japanese Yen to different country where it is not a readily accepted legal tender and give it in a supermarket. I’m sure the response would be the same as what you quoted.
The value and the next sucker part also fails for the same reason. You can exchange or even use to pay, say, USD in many countries in shops and street side currency converters of dubious legal standing. They would trade it with the “next sucker” because they’re part of a network that values USD.
