Real ID is/was needed because every state has different requirements to get one.
The whole debate is hilarious, you need one or two extra documents to get RealID. The exact same amount of time and trips to DMV.
A general reminder that every extra obstacle to getting a valid ID (or voting) disproportionately impacts the poor. They often lack the paperwork, the free time, and the money to deal with the extra process involved.
I had the option to get a "Real ID" the last time I renewed my driver's license, and did not. I forget which stupid bit of paper gave me trouble, but I had a valid passport (the Mother of All IDs), which was both insufficient to get a "Real ID" and sufficient to fly. It's a joke, a nuisance, and now a revenue source.
The fact that Real ID was introduced when I was in college and has been pushed back every year since shows that we don't actually need it.
