I wondered if you meant to write something like "Lagarde almost sounds like a Bitcoiner when she talks about the need for **nation-states** to reclaim their financial sovereignty".

This would make sense to me because I know the ECB has frequently sold the digital euro as a way to make financial infrastructure independent of US companies.

If you really meant to put "individuals" in that sentence I don't follow your reasoning as I don't think Lagarde has ever expressed much interest in individual financial sovereignty. For European nations certainly, but individual Europeans not so much.
