Alternatively 0.2 T$ could be written as 200 G$ as well. It would work for smaller numbers too: the EU's budget for boring bureaucracy for 2027 is 40 million Euro? Make that 40 M€ (megaeuros). Your cup of lemonade costs a quarter? It's 2.5 d$ (decidolalrs) now, or 25 c$.
I think we should metricize curriences to make it easier to understand larger amounts of money. Imagine if instead of saying "The national debt has reached 200 billion dollars" we said "The national debt has reached 0.2 T$ (teradollars)". It would get rid or all the excessive 0s.
