Yes, governments do want to ban cash and Bitcoin.
In the capacity of the interests of the country, I do not think the government is trying to prohibit cash completely.
That is why they create CBDC. CBDCs are inherently an element of a digital concentration camp.
CBDC is a state product, that means that it has a function that almost resembles the Fiat currency, the reason they start to develop this as well as being able to be controlled and restricted, so that the basic fiat currency that is increasingly obsolete has a revolution in the field of CBDC, but the point can also be fully controlled by them .
Also, people will not be able to save money, since the CBDC system does not involve placing money on deposits (with interest accruing over the time the funds are used).
Instead, the CBDC system will be programmed to get people to spend money as quickly as possible (buying government-authorized goods and services).
Different methods but have almost the same function and approach, I mean they try to revolutionize the Fiat currency, so that the existence of cryptocurrency does not make them disturbed and begin to be abandoned, although the use of crypto must also involve the Fiat currency during conversion.
They just do not want to be said to be lagging behind in terms of increasingly developing technological revolution, thus making CBDC other languages to participate in decentralized technology. CBDC also does not have unique advantages and functions, if true as you say, cannot put money in deposits and have to spend money as quickly as possible.
