That would be a very severe violation of the GDPR and whatever bank-privacy laws are in place. On top of that, which insurance would even be affected by it?

Yeah, buying medication is literally the only good use-case for cryptocurrencies, but it still is a valid and important use-case that saves lives!

You don’t need quantum computers for that.
