These types of services solve only a little piece of the equation.
I now also tend to think that people focusing only on privacy are individualists. A good example of individualism is defending the right to freely own and carry weapons. For rational, well balanced and honnest peoples, it sounds right and harmless as a mean of defense. Like privacy. But it is well know and demonstrated by the numbers that pople are abusing this right and using the guns for bad goals. The trust given to them, not only by the authority, but from nightbours and all honnest citizen as well has been betrayed. In europe where guns are banned and under very tight control, life is much safer. This is very counter intuitive. See ?
I now tend to assume, privacy is very similar. If we give up privacy we may become much safer. Of course there must be exceptions, but with tight controls as exist for weapons in europe. Privacy should be available to lawyers and doctors for instance.
Finally, a last missing piece of the solution is a feedback loop to control the controllers so that no one can abuse the system, and this includes the government.
