Switzerland is the easiest choice, based on location and policies, but there really are no good choices.

Anywhere you can find a chunk of land and raise enough animals/vegetables to live on will be ok, but if governments start to require exchanges to fork over funds from certain wallets, then it will be done in a synchronized fashion, just like lockdowns were. Either the people will roll over and take it, or the government will collapse.

Germany is a high-cash-usage country. Basically everything under 1000€ is done with cash, preferably. I pay rent and internet with bank transfers, but everything else is crisp, plastic notes.

I do think that the EU will ramrod their CBDC very soon, though. Especially with the passage of the bill to sign over governing power to the WHO. It's gonna be a wild ride.
