Sure, we still have the IMF, but I'm specifically referring to part referring to the "gold standard". Again, it wasn't really a gold standard because the deal only extended to governments that happened to be desperate for capital. Regular people couldn't even own significant quantities of gold at the time.

>the fiat currencies of all countries around the world were still pegged to the USD.

This isn't true. Otherwise, exchange rates wouldn't be changing every second. Countries were allowed to choose how their currency was exchanged, and most of the major players allowed their currency to float freely.

>USD to hyperinflate relative to other currencies because all countries were still trying to maintain a stable exchange rate relative to the USD.

The USD never hyperinflated at all. I think the gist of what you're saying is true, like how Japan started to devalue its currency after the Yen started increasing in value. However, this precisely shows the problem with deflation. If your money grows just by sitting on it, there is little reason to invest in businesses, and it may be profitable to even downsize your business.

>You should watch 'Hidden Secrets of Money'

That was produced by the founder of goldsilver.com, so it's hardly an unbiased source. His business gains from sowing distrust in the financial system. I didn't watch this particular series, but I'm familiar with their arguments after I started investing in precious metals. I don't think their history is wrong, but IMO, they miss the entire point of money. Money isn't meant to be stored because it doesn't do any work. Money is something made up to facilitate trade as easily as possible. That's why it never makes any sense to artificially place constraints on it (e.g. pegging it to gold). This doesn't mean that we should abuse this freedom to print money on a whim either, but that's a completely separate problem.
