In the movie the Bone Identity & Supremacy the character was completely off the grid. No phone, no driver’s license, no credit cards, no bills, no real physical proof of existence beyond his location at any given time.
Then there are most Americans who use a credit or debit card everywhere they go, have emergency GPS locaters in their cell phones, have enough ID cards to fill a wallet, trackers on cars, and are locatable just about every moment of the day. We have multiple e-mail accounts, on-line identities, accounts at several different places, and we are just short of having a GPS locator chip in our heads.
How on the Grid are you? If someone needed to get a hold of you are you just a phone call away? What about an e-mail. Additionally at what point to “modern convinces” become a short leash?
