My point is: UBI should only enable people to subsist on government income if they are willing to live in cheap areas with not-so-comfortable living conditions. Some people will jump at this chance, and that's fine. Many other people will decide they want to live in more desirable locations or increase their standard of living and will need to supplement UBI with other income accordingly. If we try to make UBI location-specific it opens up all kinds of arbitrage opportunities and weird incentives that I don't think most people want.
How about family ties? How about ties to their friends and community? These are human beings you are talking about, not robots. At a time when societal problems relating to atomization are increasingly evident (e.g. https://psmag.com/social-justice/americans-are-staying-as-fa...), we hardly need to encourage more of it.

Oooh, yes. We could also give these cheap areas with not-so-comfortable living conditions some snazzy label like, say, "ghetto", "favela" or "slum". /s
All your substantive points can be expressed in the curious style instead. Just be thoughtful, respectful, and open rather than snarky, indignant, and confrontational.
