Privacy may not be a goal in itself, but it sure would be painful to wake up one day and realise one has given it up for perhaps more trivial and ephemeral "benefits" along the way, especially if this took place relatively slowly over many years. Privacy (among other things like personal freedom, health, etc.) really seems to be one of those things many people take for granted until they realise they have lost it, or willingly gave it up, not able to easily get it back, only then realising how important it was in hindsight.
