The government only has a monopoly on legal violence, but violence is beside the point. (And never mind that a bad government could simply steal the data or compel a corporation to hand it over.) Imagine living in a state where abortion laws now allow individuals to sue other individuals who have had abortions. A corporation could use grocery data to find and sue individuals who are likely to have had an abortion. The analysis would be a bit more complex than this, but just looking at grocery data, scan for people who bought pregnancy tests, bought fewer tampons than usual, and aren't buying baby food a year later. No violence, totally legal, and absolutely devastating to the individuals involved.
