> If anything, the Dutch government has been telling people to have cash available in case of emergencies after "geopolitical tension" (read: the Russian invasion into Ukraine). Not that anyone seems to listen, but they encourage having cash reserves.

There is a very strong case for people keeping cash because of its resilience.

People will not do it until something happens to make them realise the problems - maybe cyberwar or natural disaster bringing electronic payment systems to halt.
