Let's talk again in 1-2 years. My prediction is that your premise will be wrong by this time in the EU, i.e., there users will have control over their data.
(not perfect control, but that is the same in every area where law is broken, e.g., there are burglars, but still I think you would consider being in control of your personal belongings, and nobody would argue that we should stop prosecuting burglary because many burglars will always get away with it)
I'm always willing to change my opinion based upon data. I'm looking forward to that discussion in a few years. Regardless of who ends up being "right", it will be interesting.
