No, we use congestion pricing

Bitcoin (BTC) critic and general manager at the Bank for International Settlements (BIS) Agustin Carstens advised against the issuance of central bank digital currencies (CBDCs) in a speech in Dublin on March 22. Bloomberg reported on the speech the same day.Per the report, Carstens explained that a CBDC could facilitate a bank run, enabling people to move their funds from commercial banks to central bank accounts faster, thus destabilizing the system. Another issue that Carstens said arises with CBDC use, according to Bloomberg, is the different impact of interest rates on the public's demand for money.Carstens reportedly said that this influence could lead to bigger central bank balance sheets that require a buildup of assets, which could potentially impact the liquidity of the financial markets. Per Bloomberg, he also noted that there are enormous operational consequences for the central bank in the implementation of monetary policy and the traditional market’s stability.

The central bank can move the crowds in or out with congestion accounts.  If you play at the fed, you do triple entry accounting, check the crowds first.  It is either congestion price or have regulated pre-qualified bankers, the system we have.  We change one thing only, keep the entry and exit optimally congested with price.
