This is imo the most feasible/pragmatic approach for privacy issue.
Instead fixing it by hiding the information, we should fix the actual issue that cause misery when the information is public.
My point is it doesn't have to. Ask what is it that makes people prefer to keep secret then fix that instead.
Not saying its going to be easy but at least we should spend the effort on fixing that, instead of spending the effort on hiding the information.
>society will still have its own opinions.
So we need to spend the effort on minimizing the misery caused by that
