I don't know. Although, even today, I think if Bitcoin were to be a settlement system for banks that people would probably not use it in mass, and would probably have near zero value.

In a large state like one of the "great democracies" it is reasonable to say that the people should be able,
in principle, to decide on the form of a money (like a "public utility") that they should be served by, even though most of the actual volume of the use of the money would be out of the hands of the great majority of the people.
