Thanks for the response! I guess what I'm wondering is if owning the tractor and leasing it out could still exist alongside collective ownership?
If I already have the means of purchasing the tractor for myself, I might not want to enter into a cooperative agreement with others and deal with the overhead that comes with it - especially if it were a scenario where I originally purchased it solely as a tool for myself. Let's say it were a simple tool like a scythe, collective ownership might seem like too much hassle when it would be more convenient if everyone just had their own.
