I agree with the theory one must prove harm to be able to sue. (With some exceptions, usually statutory.) I also agree it is profoundly difficult to prove damages from such a breach of information. Even if you do actually suffer harm because Missy of Oklahoma had access to your phone calls, I don't see how you can prove damages even if she is videoed selling that information to a person who is convicted of taking your bank account.
I understand there are multiple statutes out there to protect our privacy. Sensitive politicians have made the politically correct vote and created a law from unauthorized disclosure. Some even have a statutory amount of damages attached. I'm sure a clever and hungry attorney or person who wants to spend hundreds of hours may find some path to some money that will result in less than minimum wage. Even then if, only if, the fact finder feels outraged from the error. Since most people know..."things" happen and life goes on, that is a bold bet.
The reality is, you have little privacy any more. The government [I started to write a screed and quickly realized it would take more space than allowed and more time than useful. Search the internet.] corporations and bad guys have much of your information already. I have three separate and special privacy "benefits" because my information has been breached. One had to do with a full breach of my health insurance (treatments, all identifying information including social security number, salary, etc.), another had to do with an IRS transcript breach, and another had to do with me using my debit card at a place to buy things. And, those are the ones I know. We won't talk how the local police radar "just to show you are driving appropriately" trailer is taking photographs and inserting it into a data base of all license plates that drove by. We won't talk of how stores now use facial recognition to see who is coming in, and when, and then track where you go. Giving your ID to scan if you buy adult beverages or an adult rated video game? In the database and linked to the other data. At least you will get better coupons!
Here's a cool thing. While I had my own house and property, I never really felt the freedom for a BBQ. After I moved and had a bigger back yard, I decided to search for a grill. (Decided on a Webber. Others are better, but, a Webber can do most everything you want with some work.) Even though I had no relationship between my home and personal internet use and work, I found the day after I first searched for best BBQ, I started to see ads on tax information sites I hit when looking for the most recent law. Look at a recent picture of Eric Schmidt (Google boss) at a Burning Man type congregation for the top 1%. (Actually, I suspect for all beyond those just allowed entrance, the percentage is far less of the world's population.) Why do you think he wears clothes that probably cost more than your salary for a year? I make good money, real good with general knowledge of what normal people make as I do taxes. Yet, the hat alone is probably more than my free income for a year. Why do you think that is? I don't know, but suspect it is because with a few keystrokes and a combination of all the information they have access to, not only do they know your name, address, phone and social security number; but also your family, political affiliation, sexual proclivities, your family's politics and sexual proclivities (perhaps how deep they search the WHY of those proclivities), how much you spend on alcohol and other things and how much you spend just with cash (And when. Guess what a simple AI could tell about how you get money from the ATM.)
Privacy is dead. I understand trying to manipulate the best you can what those with access to your information believe. Be as careful as you like. As to if "Brave New World" or "1984" is a better meme for our life is difficult. I think a marriage of both. I only hope the good portions win out. Perhaps democracy will save us. That less than half of the U.S. knows the vice president in almost any survey, makes me think it relies on the more powerful meme.
Bottom line is that, at best, you get a service for a year or two to tell you of accesses to your credit. At best. No attorney will take it. No one really cares. I suppose we have the check that if there is a class action suit, it could cost the corporation a lot of money. Won't give you anything, but, corporations hate spending a bunch of money.
