Dear Brother
owl, that's true, however the Federal government is somewhat more competent than the average county clerk, in my experience, plus, the passport does
not have your address on it while still having
Magical Powers of Persuasion with the aforementioned county clerk & other entities.
Last year, I got a new passport (the cheaper "card" version), using my expired passport, birth certificate, and almost expired driver's license, then used it to get some other things including a Library card.
By then I had made
three failed attempts to renew my driver's license, and was planning to use the passport to renew it, but tried one other county and got the Mythical Competent county clerk.
He offered to do a Real ID, but I politely declined, purely as a meaningless-to-all-but-me act of rebellion.
Note that I'm doubly "vulnerable", both because I'm homeless and because there is a tiny spelling discrepancy between my birth certificate and other IDs. The spelling issue has been reported by many as a problem when dealing with below average county clerks.
Bottom line:
If you're vulnerable (all true full-timers are), or have the potential to become so, then it's worth the modest cost for a Passport Card.
Bonus: They're good for
ten years.
I had no problem getting it mailed to my PO box, though it did not show up in USPS' "Informed Delivery" (twerps!).
