Plenty of people only have a SSN card and a birth certificate, as they neither drive (perhaps due to age or preference) or travel by plane (often for financial reasons or preference).
Additionally, how are you going to handle undocumented persons.
As for illegal aliens, they are illegal. They shouldn't be getting IDs issued by the government in the first place, be it state or federal, and should be deported as they are found.
>Almost nothing requires double photo IDs
From experience, anything that is very and truly important has always demanded I produce multiple forms of identification. Usually 2 or more.
However, we are speaking in general rather than specific contrived what-ifs. The vast majority of people have the opportunity to obtain multiple forms of governmental identification that are accessible and affordable.
They should be, yet somehow that is never part of the plan in bills that require these IDs. And isn't it curious that the areas where these difficulties are found are almost always correlated with minority demographics? Weird.
When it comes to creating systems whose consequences infringe on rights things like "the vast majority" aren't valid escape hatches. This is doubly true when the folks making the rules have political motivation for disenfranchising the very same group who doesn't have IDs in this case. In fact, when such discrepancies are pointed out and then are instituted anyways, such biases functionally become the point of the institution and increases culpability rather than decreases it.
