That is not a critical rule to my model. If I wanted I could change it so children can inherit land as long as they can't hold multiple parcels without it effecting or destroying my model. But it doesn't really matter one way or another in my model who productive land goes to when access to the productive goods of all who participate in the cooperative model is denied to no one. Essentially, the son is already the heir to the production of every farm in the cooperative model. I mean, does ownership of a resource matter when what's really the issue is access? The only reason you think the son is losing out by not being able to inherit the farm, is because you are still thinking in terms of access to produce being conditional upon monetary compensation. In other words, you believe if the son doesn't get the farm, he will have to pay others to access farm produce as he would in a monetary system. Not so in a cooperative model. It matters not to me if I don't own a farm as long as I have access to the goods produced by all cooperatively run farms. But again, I could change that rule without any structural effect on my model.
