Sure! That could definitely be true. I'm just pointing out the essay is lacking in real alternatives to what the essay is critiquing.
What societies currently have zero homeless? Looking at western nations I can’t find a single country “without homelessness.”
The Holy Sea ;-)
Singapore has very few homeless people. Most countries in Europe have almost no homeless population. It's not zero, but it's low enough that it is not a big problem compared to the US.
