It just means that because this is a federal requirement that needs to be implemented by the states, we're going to see 50 different implementations. Some will work better than others.
My state doesn't require real id and I see no reason the get the realid compliant id my state offers. I have a passport, passport card, and global entry which are all federaly issued and "real" ids.
Why is it so hard to just travel with a passport or passport card?
Yeah not really a surprise. Most of the surveys I've read show something like 10-12% of people have never left their state, and 40% or more of Americans have never left the US.
HN is overwhelmingly technical, educated, well-off, and travels a lot -- most of the US (and other places, for that matter) aren't.
