We should simply outlaw most privacy-invasive behavior. People will still demand news, social-media etc, but the payment will be different. Technology cannot and must not solve everything.
1. Ad-tracking: we have lived decades without advertises being able to track responses, viewership etc. Ads will still be valuable for business if we remove those options.
I don’t think privacy is tenable. I think we could eventually Physically engineer ourselves to be more cooperative and less driven to harm others. This is achievable, but privacy is not stable, is unnatural, and because it is so hard to come by, striving for it creates in my opinion needless scarcity.
Trying to avoid harming others is also not tenable, but a policy of avoiding harm is capable of being followed with soft penalties, and I think neuroticism can be avoided. I think striving for privacy and it’s preservation is inherently neurotic, though it can be short term successful policy in the presence of others who would harm, exploit, or subjugate us.
