As others have said, the goal is the surveillance. But this notion goes further than that. So many ills people face in life can be solved by just not doing something. Addicted to something? Just stop. Fat? Stop eating. Getting depressed about social media? Stop browsing.

Some people have enough self control to do that and quit cold turkey. Other people don't even consciously realize what they are doing as they perform that maladaptive action without any thought at all, akin to scratching a mosquito bite.

If someone could figure out why some people are more self aware than others, a whole host of the worlds problems would be better understood.
