We fast approach the time when a corporation, or the government, or possibly a private citizen will be able to tell our whereabouts with the push of a button.
You keep alternating between two arguements:
1) We are already there so don't worry about it.
2) It can't be done so don't worry about it.
You should pick one or the other and stick with it.
The answer to your question is in the subject heading. I don't think you can argue me out of my concern, so why not give up? I promise not to try to awaken any concern on your part, any more, since I can see that you really and truly do not see an issue.
