Why do we have to "need" privacy? That's completely backwards. It boggles my mind how people keep insisting on this argument. It's the government who needs an incredibly good excuse to even consider violating anyone's privacy. Authorities think they're justified in everything they do and are developing increasingly entitled attitudes towards personal information. They can't be trusted so we absolutely should lock them out and make it impossible to violate our boundaries.

Who cares if criminals use it? It doesn't matter at all. Technology doesn't choose its users. Governments wants to catch criminals? They need to send people out there to do real investigative and police work. We're not obligated to make it easy for them by making everything we do part of some public record.
