Perhaps that's because privacy is actually an archaic and backward idea that maintains all of our problems alive. I can't think of a less progressive (more conservative) idea than privacy.
The next most important revolution in human history will be our transition to a completely transparent society.
Considering that we need to get to a transparent society, contributions to the privacy movement only ensures that the transition will be even more difficult and violent.
(I mean radical in the traditional sense, not as a slur)
Many people have written about this. I haven't read a single convincing argument in favor of privacy as anything other than a defensive measure.
The reality is that I came to this conclusion through a long process but I'm pretty tired. The process definitely considered whether the 'private' version of the world was even possible. I don't think it is. Surveillance will happen. Better we accept it and keep an eye on how it's used than pretend like we can prevent it in the long term. Even if you were able to discourage the ubiquitous 'high tech hackers' and 'big data' forms of surveillance (which I don't think you'll be able to do), bribes and drones will continue to be used for the powerful to get what they want.
In your utopia, if you ask me a question, do I have to answer honestly? That people would always want to answer honestly is not a satisfying answer.
I don't favor coercion, so nobody is going to be forced to say or do anything.
Refusing to answer would be like refusing to help someone who request your help. Considering that answering the question is relatively inexpensive, you really don't have a reason not to do so. Unless you're hiding something, which will make people think of you as selfish.
I wouldn't trust a person that is selective when it comes to answering questions. They'll only say the truth you want to hear, which will contribute to bias and poor understanding of reality.
Moreover, its just plain simpler for a person to systematically tell the truth. Seriously, the mental burden of remembering lies and keeping secrets is probably extremely underrated.
If it helps, I tend to be frank/blunt to an uncomfortable extent. I sort of try not to because people find it off-putting, but I also sometimes don't notice I'm doing it. So it's not like I am in opposition to what you are saying, but I don't necessary see that it would be so great.
