In extreme cases, if the official currencies were to go under, the Libra would follow suit. The Libra is, therefore, not a real alternative to official fiat currencies, but rather a more straightforward and more cost-efficient way to use them.

So anyone who thinks that the Libra might offer an escape from the bad fiat currencies is mistaken. The Libra is a fiat money clone; just like fiat currencies the Libra is fake money ..."
