Such short term thinking. Nothing in your post about the next fifty years. Basically everything you describe are policy choices that can be reversed over time.

Consider that Australia didn't even have a currency 70 years ago and didn't even float their dollar until the 1990s! Now the AUD is a decent chunk of the reserve basket.

US does plenty of printing and currency manipulation too via the Fed.

It's ridiculous to think that one national currency should be the international reserve. We're just in an awkward period. It will be a blend of all currencies with China becoming a bigger portion over time.
