You think your bank can't shut down your account now?
The ability to monitor every transaction you make.
You think your bank and CC company can't do this now?
The only way to avoid being "monitored" is to use cash. And a CBDC won't change this.
It is fundamentally no different than what already exists --- just faster, more capable, more convenient and less costly.
If it's really cheaper, faster more convenient then they'd be enthusiastic about doing it because it would look good for their bottom line.
Money at the end of the day represents trust.
If the Fed is the most trustworthy entity then JPM and Wells Fargo are at #2 and #3. Nobody would care if the #2 and #3 institution exchange money between each other instantaneously and 24/7/365 but only settle their accounts at the Fed weekly or bi-weekly.
This thing for everybody to have an account with the Fed in the form of tokens (digital dollars and digital euros) is something really strange and that nobody has asked for. It is the project of some beurocrat which has seen a topic of interest among the population (crypto) and wants to look good to his superior or wants to claim that "I was at the helm of the team which developed the Digital Dollar".

This thing for everybody to have an account with the Fed in the form of tokens (digital dollars and digital euros) is something really strange and that nobody has asked for.
This thing for everybody to have an account with the Fed --- is not what is being proposed. Your bank account will stay right where it is now --- just with new features and capabilities.
No banks will be killed in the production of a CBDC. If it were otherwise, rest assured you would have heard about it from your bank by now.
