Why are you being intentionally obtuse about this? What did I just say, in the very comment you quoted:
While that's a minor inconvenience for people like you and me, it can be a tremendous obstacle for many. The inevitable result is many of these people will not get that ID and will therefore become disenfranchised.
Rather than me going through what "the problem" is yet again, please consider going back and reading the many previous threads where it has already been explained in excruciating detail. It's probably already been explained several other times in this thread, come to think of it, but I just don't feel like looking.
