ELI5: Why should I care about my privacy if I have nothing to hide?

I am asked this question all the time, and I have never been able to break it down in terms that they can understand without them thinking I am a conspiracy theorist.  How can I describe the value of privacy to someone who is scared of terrorism and believes that giving up some/all of their privacy is a good thing?

Because the data that is gathered from someone's private life, taken out of context, can hurt them.

Even if you have 'nothing to hide', what is taken out of context can sometimes be damning.

Like say you had a lot of Muslim friends, and you decided one day you wanted to buy a pressure cooker because you need one for your kitchen.  If homeland security (or some federal anti-terrorism agency) mined this data, they could add you to the "no-fly" list because A) you associate with possible terrorists and B) you bought a pressure cooker.

An organization that is able to get its hands on a large amount of private information could make all sorts of inferences based on weak assumptions.  And on those inferences, they may act and affect your life.
