Out of curiosity, I searched information on obtaining a marriage license. No, I don't need one. Will never need one again, lol. But if I did, it would not be hard. Even if I lost my SSN, if I were not a legal citizen, I could still obtain a legal marriage license.
Several years ago, a friend pointed out to me that she had more rights than people who had lost theirs - or voluntarily given them up by committing crimes. But they can obtain a legal marriage.
My point is that it is easier for some to obtain legal privileges such as marriage licenses or driver's licenses than it is for others. I think it's a shame that not everyone deserving can do that.
