My particular hot take, speaking partially from experience, is that indeed, there are insurmountable amounts of data collected - but it's collected by hundreds of disconnected, inhomogeneous and incompetent organizations with conflicting goals. There's no global all-knowing conspiracy, even governmental organizations in a single country have poor data sharing capabilities. And this should be trivial - it gets much harder when you take into account commercial organizations that store user data but it's not their main focus, commercial organizations that want to sell user data, but not for free, commercial organizations that really want to pretend they care about user privacy, foreign organizations, foreign organizations from hostile countries, and everreaching bureaucracy related to getting data from basically any of those.
