I take issue with this type of argument, because it ignores that scale is the _core_ part of the problem.

Equating "an individual selling on craigslist prices based on area code" with "Albertsons buys petabytes of individual private data and prices groceries based on income" is IMO not valid. Yes the very very core -borderline philosophical- question is the same. But the _scale_ is what makes it the problem.

It's the same argument I heard a few times "Why is flock a problem? My home driveway camera points at the street and sometimes I can read a license plate!"

So much like other laws / ordinances / provisions / etc. if regulation against this type of behaviors get enshrined, they should include thresholds for scale (which I believe the Seattle one does)
