To be fair I don't like the commercial banking system but having all the banking system centralised like that is so much worse. At least the commercial bank system is in some way decentralised.

Also CDBCs are programmable, Programmable money is a dangerous tool in my opinion. The State could thoroughly control everything you could do with money (e.g. carbon allowances, money that expires etc.), money would literally become vouchers controlled by the government. Pure dystopia.
