You’re right, the article I linked to is more about how to eliminate a pesky attribute of physical cash, not the physical manifestation itself (which I’m frankly less concerned with). My initial comment was mostly meant to be about the removal of physical cash as an alternative to something with a negative nominal yield, which a dual currency does accomplish, it would no longer be an alternative. But separately, I do think the eventual intention is to also get rid of the physical manifestation entirely, with a dual currency as a way to ease toward that.
