I thought being reserve currency meant more that you had the lowest inflation impact when printing more. Given the US creates new dollar, banks then get those dollars and buy up stuff first. Hence the ability to export most of the inflation that can happen with excessive money printing.
You are right about the "printing money to export inflation", but this practice is a double edged sword. By doing so, you are devaluating dollar, which in term will threaten future borrowing. To counter that, you are going to increase your interest rate which is what US is doing now. That will in turn increase your borrowing cost which will increase your debt. Increased debt means more interest payment. It is a death spiral that I talked about
#49,728. In Chinese it is called "饮鸠止渴", drinking poison to quench thirst.
Other countries will suffer the lose of devaluated USD denoted debt, US will push its debt interest payment higher. Nobody is better than the other except countries who can replace USD's place with its own currencies backed by something solid products like commodities and industrial/agriculture products.
The bottom line is that currency and therefor wealth that it represents must be backed by physical means, otherwise it is just waste paper. No trick can save it and whoever printed it.
