The threat of a comprehensive database of everywhere I've been is extremely minimal. There's not much someone can do with that that they couldn't do without it. If some whackjob want to wait for me to turn the corner so he can hit me with a sock full of nickels or something, he's not going to get a database of everywhere I've been over the past two years and hang around the coffee shop that I have an 84% chance of visiting on the third Thursday of odd numbered months. He's just going to look up my address and wait in the bushes outside.
