I agree with you. However, digital currency is much more stronger than fiat because it is fully centralized by the central banks. You can launder those money without being caught by the authorities. Everything will become more transperency, easier to trace and you sn not escape from the government. I wonder if professional hacker can interupt the system. This can be consider as innovation of humankind although many people will be fully controlled by their country. Just look at China. Even though cbsc is just a test, citizens behaviors can easily be observed
As mentioned above, the digital currency of Central banks is only one form of Fiat currency and any opposition between them is meaningless in its essence. I think that despite the greater degree of state control over digital currencies, hackers will still find loopholes and ways to deceive the system, because the confrontation between the shield and the sword has a long history and will continue at a new technological level, because absolutely everything is impossible to foresee in principle and there will always be things that allow for double interpretation. But this is a philosophical question
