 \section{Harmful coupling with identity}
 \label{sec:coupling}
-A harmful idea emerging from the ECB report is ``combining use of
-digital identity and CBDC''. The same idea is echoed in the French report
-which quotes an unpublished report from Catenae (2020) to say that ``it is
-difficult to envisage the creation of a retail CBDC, and more specifically a
-Digital Euro without first creating a reliable, secure digital identity
-offering the necessary guarantees''\footnote{il est difficile d'envisager la

+The risk is not theoretical. After the original submission of this article,
+the Emergencies Act of February 2022 granted the Canadian executive the right
+to freeze bank accounts without judicial
+oversight.\footnote{Summary by Premier Kenney: 
\url{https://www.youtube.com/watch?v=NehMAj492SA}} The
+Canadian minister of justice David Lametti promptly used this to threaten
+people on CTV News with extrajudicial asset freezes if they were making
+significant financial contributions to a political cause he strongly disagrees
+with.\footnote{\url{https://www.youtube.com/watch?v=xoTCxWSQW30}} If this is
+possible in Canada today, we do not want to imagine what might happen in less
+established democracies if an account-based CBDC were to largely displace
+cash.

+Consequently, the question should be if central banks should limit CBDC
+issuance within the scope of their current mission instead of modifying their
+rulebooks.  Wisely, the US Federal Reserve is currently barred from
+maintaining digital account balances for individuals~\cite{usfed2022}.  We
+consider this law wise, as we argue that tightly coupling payments with
+identity is harmful.  While the law prevents the Federal Reserve's from
+issuing an account-based retail CBDC, it does not seem to prevent the Federal
+Reserve from issuing a token-based privacy-respecting CBDC.  This is crucial,
+as the technology behind token-based privacy-respecting CBDCs would
+fundamentally not support the kind of asset freezes enabled by the Canadian
+Emergencies Act.
