The US has based its prosperity in the modern era on it. The Bank of England has no qualms about directly buying the UK government's debt (and the government wouldn't dream of telling them not to : that would be political interference...)

If poorer countries do it, it's inflationary and ruinous.

Non-Anglo mature economies can't do it because... it's verboten.
