She must be being facetious, because what is the Euro? It's simply a made-up unit of account that everyone (currently) agrees can be exchanged for good and services, and other units of account (currencies). If her argument is that governments will 'back up' the currency, what will they back it up with? More of the currency? Basically the Euro is 'worth' nothing too, it's only trust. Even though I'm not much of a fan of crypto, it's essentially the same, it's just trust, though cryptos maybe have shakier foundations, and could implode with no-one even attempting to maintain their value. The big difference might be that states can 'back up' their currency by forcing citizens (with violence) to accept, and pay in their currency. An imposed delusion, rather than a shared delusion, perhaps.
