it plays off the idea that homeless people are homeless because they’re deviants somehow,

The only problem here is your interpretation of the comic.

Instead of looking at how it humanizes homeless people and shows that they are
just like everyone else you decided to interpret the guy going clubbing and being
interested in the opposite sex as the artist depicting "deviants". WTF?

Fact is that giving homeless people a sizeable cash injection and a place to live often has very good outcomes in them being able to turn their lives around.
