My point was to rethink privacy from the perspective of what we as individuals stand to gain by gathering this data. I then asked: who would you trust to gather and store this information, on your behalf? For most people, they wouldn't be able to answer that question — for others, especially technologically privileged individuals / open source libertarians — the answer would be "myself".
Aside from logging in with your username and password, you have few if any opportunities when using apps today to stream your data exhaust into a data vault of your choosing. Rare is the app maker that allows you to export a dump of your data, rarer still is one that openly shares the data it has about you with you.
Curiously, Facebook actually a lot of functionality in this regard through its App Settings page (https://www.facebook.com/settings?tab=applications). Google Takeout (https://www.google.com/settings/takeout) provides a lot of your data for export, but no one seems to have really built any tools for the individual to take advantage of this trove of information for personal benefit.
What I hear you arguing for is the end of user tracking. Indeed, there are plenty of tools that you can outfit yourself with to that end (Tor, Ghostery, Adblock, Do-not-track, Incognito Mode, and many more). But ultimately you as representative of a class of internet consumer are an outlier. There are for more people on the internet and in the world who unknowingly consent to data collection and then have little upside in the collection of that data. It is those people that Google cares the most about as customers (perhaps in addition to advertisers), and those who are most in the dark about "the privacy boogey man" about which you know plenty, but about which they know nothing but confusion and fear.
My question is how we enfranchise those individuals with the choice — either to not be tracked, be tracked by a party of their choosing, or to somehow do it for themselves so that they reap some of the gains of the data capital they are producing.
