False. Capital flight doesn't go into potatoes - it goes into money or other forms of safe havens assets.

The situation during Weimar was a little bit different than what we're experiencing today. In Weimar capital had somewhere to go: other countries. That impoverished the german economy and led to a situation where the german government decided to balance the trade deficit with new money, locking them into a vicious cycle of new money vs. a falling exchange rate.

Today what we're experiencing is that capital is trapped in a world-wide fiat system governed by the USD. There is simply nowhere to go to punish the USD, since all economies are basically built on the USD. That's why the worst thing which can happen to the USD are bilateral trade agreements, which cut the USD out of the picture. If that process has advanced to a sufficient degree, it'll be a game changer for the FED policies.

For the same reason cryptocurrencies can be considered the antidote to the USD, because it allows for direct trade settlement of any scale.
