Mainly that the market wants dollars, doesn't care how they're issued, is willing to take risk and will seek out the easiest way to make this happen.
The piece I don't think he appreciates is that this is true or everyone and Eurodollar is heavily gated to large institutions.
Fedimints+Stability pools takes this and democratises access so a small community can now run Eurodollar style system with minimal risk
It's objectively better, lower risk, better settlement guarantees etc
This is probably missing nuance as an answer :)
