I know I'm reading too much into this meme but just houses is not enough. There also needs to be easily accessible and comprehensive mental health/addiction treatment because those are pretty big contributors to homelessness, and especially housed people becoming homeless. From reading some of the accounts from the Downtown Eastside in Vancouver for example, people actively looking to get clean are being told to wait months before treatment is available, and people routinely overdose and die while on waitlists for rehab.

And if we take yet another step back, the even more important step is to address what exactly causes people to fall into addiction in the first place. A lot of the time that cause is related to the exploitative and soul crushing existence under capitalism.
