Freedom comes from having a community and the resultant government that is uninterested in your private life.
A government that does not care what you do in your bedroom and is indifferent to what books and movies you enjoy.
Freedom does not arise from an individual being able to hide 'offences' from authorities, it arises from the community not wanting to make a person's personal life subject to moralistic oppression.
In western democracies the overwhelming source of oppression comes from criminals. And only minor secondary oppression from inaccurate legal attention.
Proper means of detecting offences and freeing the legal system from haphazard targeting of the innocent should be welcomed.
That's why I support centralised databases of proper authentication such as finger prints, DNA and iris scans.
