That what doesn't exist for the license plate dataset? I am sure there are good reasons for having that dataset. For most data collection, there are good reasons.
My argument is that just because we decided that "police with camera" is a worthy trade-off, you cannot use this as an argument for "license plate scanning is a worthy trade-off". It could be that it is, but it doesn't follow from "it's a scaled up version of police with camera".
I think you are going too deep down individual tangents here. My “cop with a camera” comment was challenging the idea that datasets aren’t tools.
If the issue is purely about amplifying the danger of bad actors and therefore forcing us to reevaluate the tradeoffs, encryption and AI do that too.
