If you ban non-consensual data collection & processing then there wouldn’t be a business case for building infrastructure for it. Law enforcement would have to build it from scratch (and trick users to fall for it or pass laws to force people/companies to use it) where as right now they can just dip into the data companies already collect. The "attention economy" is the best thing that happened to intelligence agencies worldwide. Where as before they had to build surveillance infrastructure themselves (which requires budget, skills and secrecy, all of which is costly and politically risky), nowadays they get all of that not just for free but much better than anything they could build themselves.
