Aside from the usefulness: True, my GPS data can be used to trace information about me (where I eat, who I meet, which doctor or prostitute I visit etc.) however I believe that conversation I have attached home are more private and reveal notably more about me than those things derived from GPS as I might discuss the exact condition and state or explicit preferences in other regards.
Much more likely to want to discuss things in your home that are outside the Overton window and don't want recorded than accidentally go somewhere that you wouldn't want people to know about.
