True but that doesn't really change the argument.
If you think about some monarchy in old days that had gold coins circulating, then you have to ask yourself a question of why did the king tax in those gold coins. First of all they had to originate from the king, otherwise the king's name and face would not have been on those coins.
My recollection, at least for many many periods in history, is that gold coinage circulated wasn't all from a single King, and in fact could from other Kingdoms, or even individual banks that minted themselves. And ultimately the gold coinage in circulation was linked to the amount of gold mined and available, so again gold mining was key here.
his taxing wasn't for so that he can have more gold.
No, that's almost exactly what it was for. It was almost always to muster an army to go fight in some war.
