The problem is that general public does not care much about privacy. if privacy was something that general public actually cared, facebook would be not in a position it is today, microsoft would get much more heat for windows 10, and samsungs smart tvs would not sell so well.
That ^ can change. A financial crisis or a internet dooms day scenario could change all of that.
I believe there will come a day that the internet will not be what it is today (free and open).
That would change privacy implications on that level.
People have not been burned with their 401k's yet as the debt bubble and stock market bubble have not popped fully.
Once that happens and people lose trust in the legacy financial system, privacy will be paramount as more laws for reporting and transparency of one's finances will be required to an even greater extent than it is today.
Just look at the attempts to ban cash happening around the world. That is a step in the direction of an age of "no privacy".
People will value their privacy once they get burned really bad by the powers that be.
I'll add that the professionals in the security and finance fields understand that privacy and security are inextricably tied together and will not be using Bitcoin or litecoin to handle their own assets or the assets of the companies they represent. Of course this assumes that a privacy coin gets the liquidity to handle 6 figure+ transactions.
Did you say this because there is a transparent ledger (the blockchain)?
