+\begin{frame}{Why?}
+\begin{itemize}
+\item National soverenity: remove control of payment sector from foreign 
entities
+\item Limit impact of bank failures on societal financial transaction 
processing needs, especially in cashless society
+\item Access for the marginalized: children, unbanked need access to payments 
as cash disappears
+\item Financial self-determination: preserve ability to pay without 3rd party 
approval
+\item Natural monopoly: high payment fees to oligopoly or high integration 
costs to many payment service providers?
+\item Informational self-determination: retail banks fail to offer 
privacy-preserving solutions due to perceived risk
+\end{itemize}

+\begin{frame}{Why NOT?}
+\begin{itemize}
+\item Threat of ``absolute control'' over society by central bank
+\item Limit innovation in payment services due to central planning
+\item Risk to central bank reputation in case of product failure
+\item Destabilization of retail banks due to capital flight into safer CBDC
+\item Central bank lacks operational capability (especially for KYC)
