Unless you've been extremely diligent, there's no way you're going to escape a targeted invasion of privacy when someone, or some group, government or not, wants it bad enough. Trying to stop that would be exhausting and futile.
Right now, we're allowing highly coordinated, highly detailed, nearly invisible, for-profit, stalking to take place legally. There's no doubt that's bad for society. We have anti-stalking laws for good reason. It's worth doing something about the current state of things, even if it doesn't bring the tracking down to nothing. The free market and tech has failed to fix it so far. They don't have forever to keep trying. Laws are the next line of defense. Laws might not stop criminals from crimin' but I'm sure the Tim Cooks of the world aren't going to risk their company profits (or personal freedoms, if the laws are strict enough) to get a little extra info on everyone.
