Narayanan's article is valuable, but I think he's far out in front of public policy. AFAICT the default in policy is that privacy doesn't matter; that's the issue on the table right now. How to implement it or deal with challenging technical issues seem to be far down the road.

My impression and limited experience is that policy makers don't care about privacy; they don't understand it or its implications, they haven't the slightest understanding of technical issues, and they have no motivation to learn because their consituents don't understand or care.

The way it changes is if people who do understand it, such those reading HN, patiently spread the word to people you know socially, in business and to your elected representatives. They need your help; they lack the resources to study every public policy issue out there, especially those requiring technical expertise.
