For me its not about keeping my data private so much, more about making it harder for them to just have blanket easy access. I have a passport, precheck, global entry... they know who I am and where I go. But if I can make it just a little harder for the other gov agencies to know what I'm doing that's a win in my book.

I hate the excuse "since I don't commit crimes". It's not about that. If they want your info that you're not directly giving them, they can get a warrant.
