I’m not sure what exact point or points you want me to care about, but none of these charts seem to suggest _why_ we and every other country moved to fiat. I’ll admit I didn’t look at them all, you didn’t give me nearly the effort in your comment that you’re asking from me…
We moved to fiat because politicians like the indirect taxation through inflation. It's free money for them, what's not to like?
That is not why we moved to fiat. It may be a consequence, but there are also seriously consequential checks against doing it too freely.
