&gt; There just isn&#x27;t a realistic scenario in which USD has 0 value and Gold is useful.<p>This happens all. the. time. The USD lost 33% of its real value between 1977 and 1981 while Gold increased in value in real terms by 65% during the same time period. USD itself has been reasonably stable since, but there&#x27;s no guarantee that will continue.<p>I&#x27;m not a crazy goldbug, I don&#x27;t think we should go around trading gold shavings with each other in our day-to-day lives, but it&#x27;s an indisputable fact that Gold is an excellent hedge against financial and currency crises the likes of which happen somewhere in the world all the time. Hell, right now Russia is in a currency crisis where the Ruble has lost 50% of its value in less than two years.
