Putting aside how disproportionately noisy some activist types are, it probably has to do with Americans having practically no trust in one another, corporations in particular, and their government by extension. At the same time, Americans tend to value some positive forms of liberty - like the ability to say and do what you want in one moment - far more than other forms of liberty - like the ability for all people to feel safe enough to be able to do the things they want.

I’m an American living in Japan, I’ve always felt a great sense of liberty because of how safe it is here; I can live a lifestyle that would get me robbed pretty much immediately in the USA. While crime rates have always been relatively low here; part of that is because Japan got tough on crime around the turn of the century, and one part of that was pervasive rollout of automated license scanners used for reconstructing vehicle movement, like Flock. I suspect that Japanese people didn’t accept this because they don’t care about privacy - they absolutely do - but instead because they have a healthy enough social context to be able to consider the tradeoffs, and a government responsive enough to design around those tradeoffs; rather than immediately flying into a rage and vandalizing their cities like some angry Americans are doing now.

The same thing plays out for other things that would pretty clearly be a good thing, like having a real secure national ID instead of relying on social security numbers for identity verification (terrible). Can’t do it, people (as well as criminals) value the liberty of being difficult to trace far more than the liberty of not being defrauded regularly, or having a civil service that is able to do basic functions like authenticating you for benefits efficiently. Sigh…
