It's perfectly fine to wish for something without having all the answers - I don't think I should be attacked for that.
People should be allowed to say that they wish to improve something, even if they don't have the exact scientifically proven step by step way to actually implement it. We are allowed to say that wars should end, that people shouldn't die of hunger, and so on - even if we don't have the exact step by step plan on how to implement it that we can share on HN.
And sacrificing my privacy doesn't have to mean that it's open to public, it refers to actually being able to enforce certain rules. If I were to do something that's illegal on HN the authorities would have no problem finding me.
