My intuition is that if you really universalized this, everything is discarded and the idea of ownership would have to change. How would pragmatically work, I don't know (probably terribly), but a maxim in which everyone suddenly stopped owning things beyond personal possessions at the same time took up an overriding ethical system which privileged ecology at least initially seems to be univeralizible. At least, it seems to "scale" better than "I will declare this land as mine to own and control even when I don't actively use it", which is one of our current maxims.
