At the same time we should caution that the futility displayed here by some, and the 'why bother' or 'if they want it they can' closely mirror the 'I have nothing to hide' arguments. Certain agencies and groups like to encourage a false belief that they have more capabilities and power than they do to encourage futility in the masses.
The reality is, the more common sense precautions you take, the more encryption you use, the more private you are with your critical data adds up in the end to data gaps from potential abusers. Those data gaps are quite annoying to those entities, especially if they can't fill them with ancillary technology/sources.
People still lock their doors, even if a crook can throw a rock through a window and climb in. A criminal would benefit greatly if you would take the futile mentality and simply leave your doors unlocked and your windows open.. Ok?
