If you are trying to apply lessons from the gold standard era to lessons in the current era of non-convertible fiat currencies, then you are going to draw the exact opposite of the correct conclusions. There is a fundamental difference in how global capital flows work when the world uses specie flows versus when the world does not.

Here is one hint. The reason why currencies like the Spanish dollar or Dutch guilder became standards were primarily questions of prestige and minting quality as you held those currencies in your own possession. But everyone could recognize a guilder and so when dealing with a foreigner, it was easier to have them.

In that type of environment, being a global export power meant that you were a global gold issuer because you sold your goods to the rest of the world, got their gold (or silver), melted it down, and issued your own stamped gold or silver coins, that circulated all over the world.

If that is your mental model of foreign trade today, then please read a bit further in your history books, because we live in the world of non-convertible fiat money. This means that when China sells $100 of stuff to America, it doesn't get to take that money home, the money is kept in an American bank account, with the name of that chinese seller as the beneficiary of the account. It's a non-convertible currency. A dollar is always a dollar, China can't melt it down and convert it to a Yuan.

So now, to be the reserve currency doesn't mean that your specialized minting tech is being stored in central banks all over the world, it means that central banks all over the world have deposit accounts in your banking system. And that can only happen by being the world's largest importer, the exact opposite of the situation in the age of the Dutch trading empire. Your entire analysis is backwards.
