AnonyMint, thanks for this very interesting thread. I'm not sure I agree with everything you write, but you do make very valid points.
Without anonymity we are toast.
Why do you think anonymity is so important for mankind ? Is it based on the assumption that anonymity gives more freedom to individuals ?
I tend to think giving individuals more freedom is not sufficient to make a better world. I believe an essential key for a better life on earth is related to the quality of the interactions between individuals, ie the quality of the collective mechanisms. Because human is a social animal, you know

Don't you think global transparency in financial systems (thanks to a traceable public ledger) might be a good thing ? (To help fight corruption, for instance)
(by the way sorry for any grammar mistake, english is not my native language)
