You misunderstand. People say they care about privacy. And they do, in their day-to-day context. But they don't care enough about mass surveillance to make any tradeoffs to avoid it.
Why should they have to? The tradeoffs suggested are ridiculous and untenable, like "not having a phone" or "never using the Internet" which is incompatible with participating in modern society. Those behaviors don't inherently need to require abandoning all privacy, but they've been recently built to not allow any alternative.
