I blame privacy advocates for sustaining this so-called chilling effect.
In reality, the chilling effect is a consequence of poor judgement. Those who are wired correctly shouldn't fear making mistakes, and should instead embrace the learning opportunity. Only then can a person really be honest and enlightened.
Privacy correlates with intolerance. We should strive to eliminate both.
Take homosexuality for example. Having that information in the open means death in plenty of places. In addition, even in places like the USA it has become accepted only fairly recently but would have gotten you in serious trouble a while back. Culture change can't happen if any event towards this change is immediately punished. The change needs to start small in closed private social circles. Only when a lot of private battles have been won is there hope for a more mainstream acceptance of a new norm.
Take being Jewish for example. In 1920s Germany it wasn't that big of a deal if people knew you were Jewish. However things changed, different people got in power and started to abuse it. What was previously a simple case of "I got nothing to hide" suddenly turned into a question of life & death. It's naive to think that these kind of events will never happen again in any place in the world.
Losing privacy would greatly hurt any cultural change that needs private law breaking, and this includes any future laws.
As for technological progress stopping, of course it isn't going to stop. However this goes both ways. Privacy protecting technology also has progress. Any technology that reduces privacy has a counter-technology that protects privacy. What's more, we can use the same political system that could hurt us with a lack of privacy to instead protect our privacy by prohibiting/limiting privacy breaking activities.
Of course no progress just inherently happens. There are actual driven & talented people working on both sides every day. There is no inevitable victor here, there isn't even a clearly leading side yet, it's very close with strong trends in both privacy-reducing & privacy-increasing directions. Every contribution matters and it's definitely not too late to decisively lead us to a far more private world.
The fancy cyber word for this is "Opsec". If you're living somewhere where your homosexuality will get you killed, STFU. Don't email people about it. That's really tragic and wrong, but it's reality.
In an era where military supremacy has made decisive military action impossible, the reality is that ISIS type people duping the simpleminded to commit horrific acts is a thing. That's makes a vision of privacy that most people Instinctively want a threat in many people's eyes.
Yes, lots of people will need convincing to make political progress towards more privacy. The same holds for less privacy.
This is what's increasingly worrying, they don't even need you to tell it like it this, they can find about it by analyzing your everyday behavior.
It's a tragic state of affairs.
OK, let's make a deal. You permanently eliminate all intolerance from everyone who could possibly have a negative influence on anyone else's life, and I'll accept that eliminating privacy might not be catastrophic for someone. Fair?
In the meantime, the point of advocating privacy/anonymity rights is precisely that there are power imbalances in the world, and some of the people more powerful than you probably do have prejudices that would make your life worse if they acted on them, consciously or otherwise.
And regardless, my point was to provide a clearer example: that the secrecy of the password is accidental: the privacy it's protecting is the account.
You might claim there is nothing in your thoughts or actions that wouldn't mind the world seeing but that would make you either wrong about yourself, or incredibly rare as an individual if true.
Humans might be a social species but there is a colossal rift between social species and the hive-mind you seem to be advocating.
I would also be careful with statements like this;
Those who are wired correctly shouldn't fear making mistakes
Judging what does and doesn't constitute 'wired correctly' has led to some serious atrocities in the past.
