I'm surprised not many people have pointed at this simpler explanation. It's not about providing a faster better service to the customers and citizens. It's about using their privileged position as the dominant players in the market and government, to secure their power and control by taking over a competing paradigm (cryptocurrency) that threaten their dominance. In the process they will neuter the concept to fit the existing power structure.
Yup. As someone who generally believes in a lot of cryptocurrency ideals while acknowledging the vast amounts of mess -- right now e.g. "widespread adoption of Bitcoin, an inferior technology, by banks and other established players" is the precise playbook to destroy what crypto ideally stands for.
