I would and indeed HAVE opted out of that world. I live in a place where we do not have surveillance cameras on every street corner. I have no data on my cell, I had my cell’s GPS deactivated and there is no GPS in my vehicle. I pay cash pretty much everytime and I have to admit, all this combined lets me enjoy my privacy a great deal. If someone wants to be connected full time so that they may be located in a medical emergency (and they are able to connect with emergency services to let them know that he/she is in fact in trouble) then that individual should probably ensure that they are trackable by the powers that be.
I’ll take my chances and enjoy my little world of anonymity where only those I choose to let into it know my whereabouts or activities. Is this dangerous in some way to my well being? Maybe, but to quote the lyrics of that old song; “It’s the heart afraid of dying that never learns to live”.
