You make that sound trivial. It isn't just about barbies. Technology has infinitely times multiplied our communication bandwidth. Giving government complete control over the personal data of people literally makes the government all seeing eye, which has never been possible before.

You might trust your government enough to be okay with this, but don't forget that government is made up of humans, with there own personal whims and idiocricies. Do you really want to live in a world where people around you might have power to completely end you? Will you be able to speak freely in such a world?

This level of power is a very new thing, and the people on higher order (wrongly) think that it's all good and they can keep going about there business as before.

Something has to change.
