Which is why people should be very much against cashless rules.

In Germany, they are.

As far as I am aware, among all the Euro countries, Germans are particularly fond of cash.

Since I work in an area that is related to finance (think in the direction of planning/writing business applications for the banking sector), I seriously very often get asked (in Germany) whether one should cash out all the money from the bank account and store it in a strong private safe to avoid the negative interest of the banks that are in the wind.

There's a possibility that Deutchbank is bleeding money and the only way for the govt to bail it out without directly inject money is to go cashless, and let Deutchbank charge negative interest.
