There's a completely different take; Civic resilience
From an operational and strategic security POV, cash is a vastly
superior technology. It doesn't need electricity, a network of cables,
satellites and routers.
Therefore cash in circulation acts as a buffer that provides economic
stability and continuity of operations.
Also, take a look at a modern European bank note, like we have in the

Roman coins that any blacksmith can forge.
There are many good, but more subtle reasons for preserving the use of
cash, and regulating business practices if necessary to do so.
