I see your point but it's hardly an effective usage of resources. In my experience, retargeting ads produce higher CTRs than generic ads. This means that a publisher is able to derive 2-10x more revenue from the same ad space if they used retargeting ads instead of contextual ads. I agree that some level of self-regulation is in order. Users should have a way to control the level of retargeting they experience and from whom, but to remove the entire mechanism that enables retargeting will only hurt the web because ROI on ad dollars will be lower. Lower ROI = less being spent on online advertising. Less spent on ads = less revenue for publishers. Less revenue for publishers = less investment from publisher to drive more revenue, which will likely mean lower quantity and quality of content created.
