What does it mean for workers to collectively own means of production? Am I supposed to own only the laboratory I work at or everything everywhere? What if I decide to change a place of employment? Why doesn't owning it though the intermediary of the state and your representative in the communist party qualify?
I feel like the focus on the economic features of socialism obscure how socialism would manifest through political process and the question of "who owns the state" - if Cuban citizens can vote on their constitution and Chinese voters can recall their elected officials, then that's more ownership of the state than many Western democracies can lay claim to.
