An interesting side-effect of CA making the Real ID mandatory is that it will force an element of our population to either move to another state or submit to whatever nefarious controls they believe the Real ID imposes upon them.

I struggle to find something that is improved by requiring a “real ID”

You will still be able to fly without Real ID (or any Gov issued ID at all, in most cases), but you will be subject to secondary screening measures.

This is how I fly today (literally this morning).

As an unexpected bonus I no longer need to argue that no I cannot go through the machine that will fry my glucose monitor nor do they try to open my sterile medication any more.

Yes but what problem is being solved through this requirement?
