And if you understand why Austrian citizens' tracking doesn't extend across all of the EU, maybe you'll also understand why it doesn't happen across the US.
What feels like time travel is going to Europe and having to use cash everywhere in Portugal because cards are so rarely accepted outside of big chains. Felt very backwards.
While CC companies have no means to jail you, locking down your credit card access in a mostly cash-less world can be a real pain - and unlike governments, they have no (somewhat) independent appeals process.
Trying to insinuate that the degree of differentiation between states is the same as between Europe countries is utter absurdity. Clearly, trying to track healthcare across different governments with different languages and different cultures is much harder than trying to track healthcare across different states with the same language, the same national government, and a very similar culture.
