You are right, of course, that most of the accounts at the central bank are digital. Also, 'money' is a loose term and 'digital money' much more so. I used the term loosely since fully defining it would take a lot of time and space.

The difference of the initiatives, such as the 'e-krona' project, comes from central banks asking themselves whether the public at large could have an obligation, direct from the central bank, in digital form. Most cash is an 'obligation' to some central bank, a guarantee backed by them. Yet no individual citizen can hold a digital account with the central bank. A natural question is 'why not'? Up to now, it has been mostly practical, that the bank did not want to have to run a retail system. The rise of digital currencies has opened a new possibility: the central bank could run the system and not need to run retail operations. Thus, the research and experiments.
