I'm getting the impression that you didn't even read my comment or follow the link.
Anti-property could certainly involve socialized housing, but does not necessarily involve that. Property is a fundamental element in our social and political systems, and serves as a basis for every form of discrimination that exists within those systems. Anti-property could be limiting that effect -- via rental regulation, shelter security subsidies, more robust social welfare programs to mitigate the harm and likelyhood of shelter insecurity (like disability) -- or abolishing the concept altogether through yes, public ownership of shelter, but also through mutual aid and kinship organizing. The reason why I wasn't specific is because I don't necessarily subscribe to a specific set of politics to respond to the issue as much as I recognize the need for Canadians to address property as a fundamental threat to human life, instead of a glitch in the system.
