They are, in certain cases, essentially enclosing the commons. There are some villages where people are peasants and when they move they can't go back. Now, it's essentially voluntary and this isn't necessarily a problem in a socialist society where they have a plan to take care of them, provide jobs etc., but its certainly not a process without its pitfalls. It seems to me they are handling it as well as could be hoped for considering the massive scale of the project.
