I am homeless, and so, my original comment was not merely hypothetical. I live in Philadelphia, which is, according to Wikipedia, the fifth most-populous city in the United States. Texas sounds rather laid back, but that's not the way it is here. Every day, I feel as if I am "an outlaw, flaunting convention and decency" because not having what's considered a "legal" residence is generally seen as a major indicator of there being something seriously wrong with me. Lacking a fixed address should not effectively make me a criminal.
You mention MBE. I just went to their website, and the first thing that catches my attention is a news item [1] stating that I need to show ID to send a package, via UPS, from an MBE location, unless I already have a shipping label prepared from an existing UPS account. On a related note, this reminds me that FedEx here doesn't take cash. Anyway, there doesn't seem to be an MBE in Philadelphia, but other mailbox places that I have come across all require ID [2] and most require me to fill out a form [3] which tells the Post Office that the mailbox provider has my authorization to handle my mail. It is impossible for me to (honestly, legally, or however you want to put it) fill out that form. Also, even if I could, somehow, get a mailbox, it would create yet another red flag on my credit reports, because the credit agencies mark, as suspicious, any address which receives mail for many different people.
I've been removed from life's DNS. :(
ICANN you hear me?
