Really? Seems I can’t step a millimetre in a doctor’s office without them asking if I’m allergic to anything (turns out that being allergic to stupidity isn’t an issue when it comes to medical treatment).

Life hack: use the one your doctor prescribes.

It was the style at the time.

Yes, for various reasons it would be beneficial to have a global government responsible for global issues. However, until such time as we have one, local currencies are going to be the best bet.

First of all, hyperinflation hasn’t been an issue in any modern economy for decades. We understand more about monetary policy than we did in the 1930s.

Secondly, economic crises did happen prior to Bretton Woods. In fact, they tended to be more common, and more severe.

Finally, it is not obvious at all that “universal currencys (sic) not run by local governments” could do better, especially given our experience with cryptocurrencies, all of which are extremely volatile and not suitable as a currency for that and various other reasons.

We need better alternatives

Why? Modern fiat currencies do exactly what a currency needs to do.
