Think creative, be less grumpy thu&¤#
The best thing about a monetary union is that with relative ease, you can manage your banking affairs in a different country, for example, where the anti-cash sentiment is not yet as strong; if that's the aspect most important for you. Today, there are 7+2 countries in the EU where cash transactions in any amount are still legal. You may even find specific items on the bank's price/tariff list regarding cash transactions of 6-figure sums which is a pretty︀ strong indicator you can withdraw those sums, if you have the money, if the bank︁ has the notes, and if you wish to do so.
If you're harassed by baguette︂ eaters in yellow vests, or wooden shoe fanatics who happen to love the orange color︃ more than yellow, go to the hearth of the EU. You may even stumble upon︄ Juncker participating in a bar triathlon. There are other, strategically located, cash hotspots for the︅ Scandinavians, etc.
