Yeah.. another way to say it would be:
Giving things (especially means of production) the attribute of property, "being property of X", is a contingent human decision. It's ONE specific way of organizing the handling of things (tightly connected to the idea that the "owner" uses the given thing for his*her own benefit).
Another way of organizing things, aka mode of decision making regarding ressources (nature, labour, and its products), production, distribution would be having a king that tells everyone what to do. Another option would be democracy: "Oh dang, we got a tractor over here. Let's see how we can use it best to fulfill the next important need"
That way you are right, your community (feat. You) would decide what to do with your tractor. Depending on how long capitalism would be gone at that time, people just might look at you a bit puzzled when you call it "yours". You know, since the idea of you being given the power to decide over a tractor you didn't build and can't consume, is quite weird ;)
