I think the EU, and the US too, are a long way from being able to make cash illegal or otherwise remove it from use. They may convince some people to abandon it and use some form of digital currency, but I don't think they'll be getting rid of it any time soon, if ever. Just because it's someones true objective to get rid of cash doesn't mean it's going to happen. It's been someones true objective to get rid of guns in the US for many decades now, and you can see how well they've done. Every time they ban one in some jurisdiction, the population responds by buying 25 more in the next jurisdiction over. Everyones grandmother owns an AR now.
