"all non cash transactions. Which you kind of have to do to with any sizeable quantity of money (say over 100k)"
Sort of related, in the Netherlands, we will soon (2 years or so) have a ban on cash transaction of more than 3000 euros. Not to one-up, just saying that it's happening. To be fair, I contribute to this by doing pretty much all payments electronically. Just like I contribute to local bookstores disappearing by buying from Amazon, although I claim to like local bookstores.
Interesting; I believe the creation of the 500 bill was at the request of Germany. This is the second visible 'give in' from Germany after not getting their candidate at the head of the ECB. Makes you wonder what they have traded this for.
