They have a narrow world view beyond their tech expertise. I saw somebody criticize BTC because they couldn't imagine using so much energy "just to secure money". I was like what you just took for granted is perhaps society's most important need and unsolved problem.
You do know there was no printing in the middle age. Good old days these all were.
Oh come now, there was plenty of printing in the latter days of Rome or Wiemar Germany and people managed to starve just fine despite it. Inflation correlates with optimistic times because it implies a debt taken on today will be easier to pay off with money earned tomorrow. That doesn't mean printing money reliably makes people optimistic.
see China's Evergrande crisis as an example.
It can barely keep up with the very few transactions now. Its transaction costs are sky high
Just because it was the best financial technology hundreds of years ago does not make gold, artificial or not, the best financial technology for today.
"Faster horses"...
Being able to trade gold without technology.
The energy to mine gold is much less (strange, very strange)
