The central banks of many states are already doing this to varying degrees. Some are just conducting research on this possibility and necessity, others are already actively creating their own CBDCs, and others are already on the verge of testing and releasing them. This process has been going on since about 2019, however it is quite long. Some states are in a hurry with their release, others are not. However, I think that soon almost all states will have their own digitized currencies, because their effectiveness in comparison with non-cash payments of states is obvious.
