In the special emergency of the coronavirus epidemic, I might consider
tracking justified as an emergency measure. It could, potentially,
save thousands of lives, maybe even millions. I would pay the price
of being surveilled to achieve that — if it were used only to prevent
the spread of the epidemic, and would be removed when the disease is
eradicated.
But once a country gets people used to surveillance, it won't stop
surveilling people, and mission-creep is sure to follow.
Meanwhile, the US government uses location data from a commercial
database to track unauthorized immigrants. The database is fueled by
malicious phone apps.
