To hypothesize then we must distill the question down to its essence...

Since gold failed to sustain itself in human organization, would the world be a better place if humans were less flawed to such an extent that gold were actually an effective money. Then sure the obvious answer is yes, less shitty humans would improve a lot of conditions.

Something we can credit gold with are the lessons learned from it to improve ourselves. It failed, but at least it failed forward.
