I'm not entirely averse to the world you describe, and you may be right that it's in our future no matter what we choose today. But... Citizens of oppressive governments are in very real danger if they have no privacy. When the secret police are listening in to everything you say and ready to whisk you away at whim, there can be no dissent nor hope of reform. Gay children of highly conservative parents are in very real danger if they have no privacy. Suicide rates in that and similar demographics are disturbingly high, and today many get through simply by hiding their identity until they're out on their own. That's not an option in your world. Anyone with minority views on contentious issues relative to their neighbors or co-workers is at risk if they have no privacy. Sometimes the most effective solution when you've got to get along with other people is just to stay silent. (I live in a small, rural town, but my values are closer to those of my friends in places like San Francisco. A whole lot of people here would be suspicious or hostile if they knew how much our worldviews differ.) I could go on. But in general, the people who most need privacy are the ones who are most different from the people around them. It's much easier to set privacy aside when you're surrounded by people who are already happy to accept you for who you are. Maybe there's another stable society to be found with no privacy at all, as you envision, but the road from here to there is steep, and rough, and has dizzying cliffs on either side.
