It is meaningless to assert as an objective simply creating a society that is "better".
Further, not all leftists defend land commodification.
Not all leftists defend markets.
Not all leftists defend money.
Not all leftists defend the state.
Final objectives are less valuable than criticism of structure and strategies for transformation.
As I have suggested, by my own characterization at least, the entry point for leftism is criticism of the class structure of society, embodied in the social construct of private property, that is, particular resources or assets being utilized socially but controlled privately.
