Does it? How so? If anything it showcases some of the trials otherwise unknown to those who don’t face them (eg weather, tent mold).
An actual homeless person would have a quite different experience of a bust.
"I decide who is homeless and who isn't in retrospect by analyzing whether something happened to their tent in the woods or whether they were not discovered".
If was an interesting read and experiment, but it has its limitations as a real world comparison to homelessness.
Also, virtually all the "real homeless" I met went to the gym to shower.
