He better be careful what he proposes, or maybe he is a "wolf in sheepskin" pretending to be your friend just like Satoshi.
The governments are slowly phasing out cash. Europe eliminated the 1000 EU bill and ATM daily limits continue declining in all countries.
While I have to agree with the statement that governments try to get rid of cash and push digital payments, I can assure you that I've never even heard of a 1,000 Euro bill existing (and I'm from the Euro zone and have had all other denominations in my hands multiple times already). So you are wrong there (maybe you are thinking of Canada or Switzerland?).
