Privacy is, contrary to much discourse particular on HN or the tech circles in general, primarily a tool for the powerful. (this is why crypto-anything has always interested libertarians moire than everyone else, they correctly recognize that it is a tool to escape (fiscal) authority).

Transparency and expansion of the public sphere generally has equalizing effects, expansion of the private sphere the opposite. This is I think relevant in particular for people in the US who seek to emulate Scandinavia, because they ironically seem to be some of the biggest opponents to anything that conjures up notions of 'surveillance'.
