I appreciate your post and it got a lot of good elements in it. I would like to highlight how the movement in Berlin to withdraw the housing market from capitalist control can be seen as reaction to the struggle against the neoliberal marketization and privatization which enables the conversion of capital to land and vice versa. As such the struggle naturally has to not be happy with small steps, but has to remain as goal to abolish capitalism as only then will the attacks of capital against the materials necessary to reproduce to generate a profit stop.
