No, the "ruiners" are the ones who impose large costs on the system. Some people are just trying to live peacefully on the streets. In large enough numbers, yeah you'll get people treating public spaces poorly and it'll cause public health problems. The key difference is that people like this who are living on the streets intentionally, if they get kicked out of the area they're living in or if the friend group gets broken up, they'll just go back to living in regular housing. Things like housing centers aren't useful to this group, but if you have cops go through arresting people they will go away. (For what it's worth, my source knowledge here is totally personal and anecdotal. When I was a new grad student at Berkeley I was surprised when a roommate of a friend told me he had recently spent a few days on the streets. He explained to me that he did this often, panhandling to make some extra money, thought it was generally fun, and met a number of people doing it for similar reasons.)
