I didn't watch the video mostly because I don't know what it contains and I have kids around. Making the assumption that it's about people who want to be homeless, honestly that's fine. There's nothing inherently wrong about being homeless if that's what you want. The problem is people causing public health issues because they defecate in public areas, tear apart trash bins, or cause other issues like attacking other people... none of which is acceptable to society. These people may not want to be part of society, but they are living where society exists.
