Sorry, I consider weak this argument. There is no relation between privacy and your "marijuana argument". Hypocrital laws weren't created because of need for privacy. Neither social stigma has nothing to do with privacy. I agree that there is a need to change a lot of laws and get rid of social stigmas, but... To try to relate privacy with wrong behaviour (unfair laws, stigmatization) is a false equivalence. I won't say a thing about brainwave capturing technology. I guess it is not easily feasible without isolating the target person, because all the "brainiac" background noise in crowded areas.
