I cannot be sure, but I think he as arguing about it at societal level. This is my interpretation:

Given the technological improvements, privacy is unsustainable. If everyone realizes this and accepts it, we can reap the benefits of transparency. In a society that does not hold bad actions against those who already paid their due fine (or served the due time). Neither does that future society discriminate against people who are different. In that society, privacy will probably be beneficial only to the dishonest.

Now, I personally don't think if we can reach that stage of maturity, not anytime soon at least. But I think we are moving towards it faster than before and we are doing that because of the easy access to information especially the kind of information that we would otherwise keep private.
