1. Having spare cash around is important to be able to acquire necessities in case of a temporary failure of electronic banking.

2. Making a 3000 euro cash transaction in this day and age is suspicious and we'd like to know about it if it happens to ensure everything is above-board.

I don't see the absurdity. They're not saying don't have cash, they're saying don't use cash for large purchases but keep some around for necessities. Even if you have 10k stashed under your bed in case of ~situation~, you're unlikely to be making a 3000 euro purchase in an emergency situation.
