Really, why is it that governments feel they must track our every movement, our every interaction?
The answer is that governments - no matter how well they start off - all eventually end up seeking
to fully control the lives of their citizens: it seems to be some sort of unavoidable emergent property
of large aggregations of people. The idea of a citizen having some degree of personal sovereignty
just falls by the wayside and everybody just gets swept up in the imperatives of the government.
This may seem innocuous - or even benign to the naive - but the long term result is that it is a
seeking of control for the sake of having control. Being traced like this can hardly be considered
to be in the best interests of individual people.
