How do you even make a meaningful comparison to the "size of the economy"? What was the price of an air conditioner in 1850? Effectively infinite, it didn't exist. Clothing used to take hundreds of man-hours to make and clean and repair and it's almost disposable today. There's so much more like that. If the economy is "bigger" in some sense, it's not just that there's more activity going on, but there are also entirely new types of activities that weren't even possible before. It has nothing to do with the number of atoms available.
