Most of the information out there is from public records... nothing to be done. You might be "lucky" to have a common name.
Identity theft might cause a headache, but probably minimal chance of headaches if your credit files are locked. I'm trying to think of how someone could act as me, a realistic scenario, realistic motivation. They can't leverage my credit rating. Identity theft is about leveraging reputation of one sort or another. Someone could parade as me on a social network site, but why me when there are so many people that are juicier targets?
The there is hiding from either true or false impressions that a search would reveal. But who's searching that I care about what they think? I guess if you had something "bad", you'd want to minimize exposure, but if it's public record, it's out there and no way to put the genie back in the bottle.
As to 'privacy', I just wonder "who would be interested enough in me to care?" Let's say someone combs through the Internet and links a bunch of stuff together and emails and calls you to give you an accurate picture of your life, including visits to the gentleman's club or embarrassing web sites, for example. Please add other examples. Maybe, if you had less than a healthy relationship, you could be blackmailed? Would not work with most people, and so seems like a hard way to make money.
I'm just not seeing the case that your details being "out there" is a big problem.
