This is an intellectually and morally deficient position to take. There is no moral principle in any system anywhere in the history of the universe that requires me to bind myself to a contract that nobody else is bound to.
We can all agree, as a society, "hey, no individual person will graze more than ten cows on the commons," and that's fine. And if we all agree and someone breaks their vow, then that is immoral. "Society just sucks when everyone thinks this way" indeed.
But if nobody ever agreed to it, and you're out there grazing all you're cattle, and Ezekiel is out there grazing all his cattle, and Josiah is out there grazing all his cattle, there is no reasonable ethical principle you could propose that would prevent me from grazing all my cattle too.
