I thought it was a rational look at what the Eurodollar actually is and what the difficulties of finding an alternative would be. I saw a pop up onscreen of the bitcoin manual article, https://thebitcoinmanual.com/articles/bitcoin-float/ , and think he linked that as a way to show that perhaps(?) Bitcoin's supply transparency is a positive where the Eurodollars supply is way more opaque. I agree with his assertion that in the near term there doesn't look to be a viable alternative to Eurodollar system yet and I do differentiate between the US dollar and the Eurodollar.
