Maybe we do need an intrusive government? Maybe we, as a populace, believe that the data will save lives? That the cost of it existing is worth it compared to the cost of not having access to information on ~insert bad person here~. Maybe you value your privacy differently to us?
That's ok, btw, and I respect your point of view. Please, however, consider that alternative viewpoints are valid before telling everyone else what they must do to ensure their country is governed in a way that suits you.
