Agreed (and sorry for the edit confusion). My qualm is that people aren't intricately aware that it's happening. Because technology makes it so efficient it can happen wholesale, at little (compared to physical 1 on 1) expense.

I also agree that tracking could be beneficial. But, if there were an inflatable robot that popped up over everyone's shoulder when they were being tracked for this convenience, there would be a different opinion, IMO. Right now - likely because it's so new - the general populous has no clue what they are trading for such convenience. That - to me - is the problem.
