Hunger, exposure to the elements, illness, death.

I missed that part of the article. What are you talking about?

I'm talking about what it means to be homeless and not owning anything.

so, living in a home I own makes me lack some sort of freedom? If yes, what would be it?

The freedom to decide one day to just leave.

In my mid 20s I maintained a not-too-extreme minimalistic life style where I could pack literally everything I owned into my car. I could decide to just leave and lose at most some months' worth of rather cheap rent.

I never actually did use the opportunity, but it gave me a lot of comfort knowing that I wasn't stuck somewhere, that I could at any moment just leave.

If money is of no constraint I guess nothing. Otherwise moving is not easy anymore
