ID is usefull to have for many non-nefarious things. If you don't have a driver's license, what else is there?
Up here, we have 3 forms of photo IDs that you can use to identify yourself for things like voting, banks, dealing with police, getting into bars etc.. Dr.License, Medicare (Sun) Card, and Passport. The 1st and 3rd, you don't need to have at all..especially if you don't drive and don't leave the country. The 2nd, most people carry on them at all times. You never know when you can get hurt and need it. It doesn't have an address listed, but between the photo and the name, it's sufficient for most ID needs. It's not traceable at a distance, or anywhere that's not medically related (Hospital, Clinic, Pharmacy, Morgue)
Now... y'all don't have Medicare cards..so what do you use if you don't drive and don't have a passport?
