That is hardly the worst case outcome. The worst case outcomes would be those where that data is used against you because it was sold/leaked/subpoenaed. There's no end to the ways it could be used against you either.
Maybe a future potential employer doesn't like how often you visit bars, or what church you attend, and you are passed over for a job you want.
Maybe your car's recorded proximity to where a crime took place makes you a suspect in a crime you had nothing to do with and it costs you tens of thousands in legal fees to clear your name. (similar to what happened to this guy: https://www.nbcnews.com/news/us-news/google-tracked-his-bike...)
Maybe that data gets pulled up in a divorce or custody battle. GPS records and toll transponders are already being used in such cases to show things like patterns of working late hours, visits to girlfriend's houses, or undisclosed income
Maybe that data is used by advertisers to more effectively manipulate you into parting with more of your money.
Maybe your insurance company (health or auto) buys it up and their algorithm decides to jack up your rates because you hit up a fast food drive thu once too often or you speed too much or drive to many hours.
Maybe you visit or even park too close to a gay bar, mosque, or planned parenthood and you get harassed by an extremist group or dragged into a Texas courtroom.
Because the data never goes away, it can follow you for the rest of your life and be used by others again and again at any time in whatever way the person who gets their hands on it feels will benefit them.
> Agree to disagree. If the cost of loss is low,
Everybody is free to decide for themselves what level of risk is acceptable to them. With some kids you can tell them that the stove is hot and they will leave it alone, while others have to touch it and get burned.
I hope that you never suffer a consequence that makes you regret the data you gave away, assuming that you can trace it back to that data in the first place. At least you can say you were informed about the dangers and made an informed choice to roll the dice. I worry a lot more about the folks who don't even realize what data is being collected, the ways that it can be used against them, or who assume that they can count on laws and privacy polices to protect them from harm.
