It takes a lot of chutzpah to claim that all economic badness arose from the Nixon Shock (US going off the gold standard in 1971) when several of your graphs show clear inflection points happening at very different times (e.g., 1981).

No, and the graphs don't even correlate. Scroll through and you see that 1971 is not a significant point on most of them.

You need a whole lot more history than you can gather from graphs to understand what is happening here.

Yup. Turns out reality is complex. Most of the time, anyways.

Going off the gold standard isn't EXCLUSIVELY crypto-currency related, but yeah, that community seems to harp on it a lot. My guess at a reasonable conclusion is "dang, there was a lot going on in the 70s, economically speaking."
