I've significant amounts of time living without a static home. In 2014, the longest time I spent in one place was 2-3 months at one particular low end hotel, not really by choice (prepping and recovering from spine surgery). Significant chunks of my time were spent living in shared housing - 8-12 bunk beds to a room, no real privacy, shared baths. In the west, if such a living space were filled with crazy drug addicts, it would be called a homeless shelter.

When a westerner has this experience in Asia it's called "backpacking" rather than "homelessness", and most folks will object strongly if I were to describe myself as homeless. Perhaps we should come up with a similar term to describe it when folks do it in the west and similarly compartmentalize their experiences.
