In my experience, normies don't care about a lot of the things Bitcoiners do on paper: privacy, censorship, freedom, etc. They DO care, they just don't know or realize how important these things are to their lives.
Bringing up privacy/censorship concerns doesn't really work in my experience. We do live in a age dominated by Apple/Microsoft/Google, etc. after all.
I've heard this from normies far too often: "Well if I don't do anything wrong, what's the problem? I don't have anything to hide!"
So when CBDCs do inevitably leak their way into the mainstream, what would you say to them to emphasize the dangerous precedent that CBDCs introduce?
