This was me being sarcastic. Of course we need privacy, not because we have things to hide, but because individuality can only flourish without constant surveillance.
Yes! All things come to an end and that is why some recent philosophers think that Plato was naive to think it could minimize or erradicate society rotting. This is where negative utilitarianism comes in, where the point of society is not to maximize happiness (and therefore prevent society from collapsing) but to minimize suffering (and therefore provide mechanisms to minimize damages from transitions between organization forms when society collapses). I have to refer you to Karl Popper's The Open Society for this, because needless to say this answer is very reductionist.
