You can't go to Google and say "I want to buy a dataset (anonymous or otherwise) of males aged between 18 to 34 who likes cars and drink beer". You can go to Google and say "here's an ad I want you to show to a group of people, none of whom will ever be identifiable to me in any way, who are male aged between 18 to 34 who like cars and drink beer."

I do have my own concerns about bulk data collection. I've mentioned in other posts that I used to do everything I could to avoid being tracked online, but have since changed course to allowing google to track as much as they want. My reasoning is that if I am at risk of being deanonymized in a way that would make me uncomfortable, it's the service that gets the most information from me that is going to notice first. If that is a service that is responsible in its reporting (e.g. I can look at what is tracked about me and make my own conclusions), I'm better able to protect myself from harm. I am, of course, concerned with giving even a responsible corporation all of that information for the bare reason that even responsible corporations hire people who are not quite so responsible. But I would rather have knowledge of what can be known from my history, than fight off everyone who attempts to track me online. At least, as long as there is a strong incentive to track people who do not want to be tracked.
