Absolutely "governments" have always been in control. How do you think they get the gold out of the ground? An elite hires people to do that work. The elites are the government in these ancient times, and they always controlled the mines. That is literally the very first thing they go for, and we have plenty of evidence for this. The precise locations of these mines was not unknown to these peoples by any stretch of the imagination.

Further, these gold mines were not simple operations, they required skill and aptitude to extract and form the metal into it's required physical form, indeed just the process of what the physical form should be is itself a complicated political process. It's also a myth that this is something recent, we simply don't have the archaeological or written evidence to know what they did, but that doesn't mean that local elites weren't controlling the monetary supply through various rhetorical, political and/or physically coercive means just as their distant Sumerian progeny would end up doing. We have evidence of direct economic control going back almost to the very beginning of civilization.
