>means that even chairs and rockets share some attributes (helping you get higher), the difference between them is still qualitative, not quantitve. I don't think so, because the needed 'quality' is the ability to traverse space. So I don't think I agree that the qualitative piece is missing. Perhaps the moon example is helpful here because the real solution, a rocket ship, uses propulsion rather than sheer mass, and…
They are qualitatively different because the rocket can traverse that amount of space scalably. The chairs cannot.
Basically, the Saturn rocket was more or less a simple chair with some extra features added to it.
Granted they didn’t stack chairs. But, nevertheless, focusing on the mods you’d need to make to your La-z-boy to get to moon would be a fruitful way of approaching the problem.
