I think communist in this song represents the idea of sharing everything. In combination with songs like "Oh, Comely", you get the idea of a girl being used, and used by many people. She's passed between people, like a prostitute, as if she is one of the possessions the communists' share. The idea that the mountain tops are her breasts continues this...she's used and then left, and she has to see if she's still alive in the only way she knows to be alive--as a sexual object.

That's my take on it, anyway.
