This was downvoted while there was an interesting point made. Suppressing cash means you no longer own your money. You only own credit lines to a private institution that can fail (and that charges you money when it doesn't). This is a stronger change than it seems. If some deposit banks are public, at least you can have your money labeled as government debt (which it already is when you hold banknotes).
