I think most governments should also stop using cash/fiat because it is also used by criminals, mostly. There's always this taboo about Bitcoin that it's always negative for having it. Those days were gone and it's more now on the mainstream and they should stop comparing it with their cash. Bitcoin can also be used the same as cash for good transactions and not just with the bad ones that they can think of. And if they are even thinking of most transactions being done by criminals and illegal activities, it's being done through cash.
