> The "quiet homeless" who can hold down a job are also likely to be able to keep track of a phone or other two factor device.

While I agree that there's a lot of generalization here, a lot of the point of supporting the homeless in the first place is that big tech should support everyone, even if they are indeed someone who "can't keep the same cell phone number for more than 4 months at a time" (via the source twitter thread) as if they're a government that must cater to its citizens.
