I think our biggest enemy to absolute privacy is "comfort".  If you think about it, comfort and convenience created the "check" system, credit cards, loans and all sorts of nifty protocols and gadgets that make our life easier and quicker. Every time a true piece of software or technology comes around that provides true privacy, we start to nibble away at it, to make it easier to use, or safer to use.  We constantly exchange our personal rights and our personal privacy for a faster internet, or a quicker login to Facebook.  I, myself, have a huge number of saved passwords and logins, to avoid memorizing and/or writing them down.  I keep a good solid hold on my computer protection, but the most private way would be a pen and paper record. I speak for myself, and for a load of others, when I say that it is truly hard to embrace the ideals we speak of to the full extent, when technology has made life so much more convenient.  There used to be a social media question that people would post and share to the idea of "Would you give up the internet for a year for a million dollars?", something like that, and most people would, but the subtle little things is what gets you.

It's hard to be the person we want to be and the person we have become at the same time, maybe one day the two will meet.
