I didn’t understand it either until:
My son lost his SS card- he doesn’t drive because he is mentally impaired- he is higher functioning-able to read, write and get around on the bus. Doesn’t drive. Anyways, for him to get his State ID he needed his SS card, to get a replacement for SS card he needed a photo ID that had his birth date and his SS # on the card. Took him a month before he found an old bus card that had that information on the ID.
So there are folks that can’t get a Photo Id due to the above example. Also, if you owe fines(unpaid parking tickets, court fee’s, etc) you can’t get a State ID until they are paid.
I learned also that you can only get a maximum of 10 replacement SS cards in your life-time.
All registered voters have their name at the local polling places. You can accompany your son and verify his address.
You can even accompany your son to fill out the ballot.
He will be recorded as having voted. That’s all.
When I went to DMV for a name change, they only needed my marriage certificate. SS just needs my state ID with my new name. Just had to do it in the right order.
Oh, and when my son got his license, he needed his birth certificate, not his SS card.
