I guess if you are the best country in the world, then deficits may not matter much ? The ultimate thing is to have the most advanced technology in the world - and also other technology which every one wants to buy. If you want to create things that no other country creates - that gives value to all of population the world - be it an iphone or the internet or boeing or php or c++ or LCD or USB or Netflix or Amazon or cisco or android or 5G or Mobile phone or AI or Quantum concepts or Carbon fibre or any other such technology, then deficits may not matter (not on usual scale I guess - if it goes like 1000 x GDP maybe it would matter). I am not an expert so.
On the other, the currency must represent something of value. It is fundamentally meant as convenient replacement to barter system. Instead of exchange wool for milk, you get a currency the value of Wool so you can get something you need other than Milk or something. So what is to the value of the currency that is given if you simply print it to represent blank or like that ?
Ultimately the question is would it be sustainable. And do experts really exist to confirm this.
One of the most well thought out, salient posts I've read in quite some time. Bravo !
