Banks are stealing the value of our money and so will this CBDC. But not for long because money will now be reliant on the crowd using it.
In crypto, I think it was the people who give value with it and not the market. The value of cryptos will also depend on our actions. The market only shows the data's or the outcome of what we do. CBDC's value on the other hand was created by the banks or backed by the supply of the fiats that they create. It doesn't depend on the crowd like on what we have with cryptos.
