I've been to a discussion about house occupation and vacancy recently and one take home message for me was that it's better to frame this topic about vacancy than about homelessness. When we talk about homeless people, we talk about scarcity, people wanting to take something away from us. Once we talk about empty houses, we talk about mismanaged abundance. Let people use houses of the rich they don't need anyway, they don't even use but rather leave it empty than let poor people in.
