I don't think the scholastic philosophers were thinking the precise balance would happen in reality, but rather the very concept seemed absurd. That's the nature of intuition pumps. Not exactly a cut and dry deductive argument, but they show certain conclusions are most compatible with what seems to be common sense. And a general principle in philosophy is to try disrupting common sense conservatively, that on balance if one worldview is much more at odds with common sense than another worldview, the latter is preferred.
