This feels like you intentionally gave this the least charitable reading. Obviously, I do not think that you could just scale to infinity. If I had said that eating a banana was healthier, I don't think it would be reasonable to say that assertion is ridiculous because that would mean eating 1,000 bananas would make someone the healthiest person. I was pointing out the difference in economic activity, where additional money to a wealthy individual mostly goes into savings/investing while additional money to low-income individuals mostly goes directly into consumption, and that the higher consumption generates more economic activity.
