I call the team I root for mine. I act as if I was a part of the team even though at best I'm in the stands. Even if I was to be forced into a mine, which yeah of course I don't want nor hope for communism to lead down that path, I bet I still would feel like a part of that mine is mine (no pun intended). The same would be said for if I worked on a farm full time.
Saying 'my farm' for the farm you work on that the people (you) own under this theoretical communism isn't wrong.
Indeed, that's what I am arguing for
And remember that communism is the ownership of the means of productions by the workers, so as long as you work there, it can be your farm in an owning way too
