As I said, one atom per digit is not really natural. Just two atoms could encode an infinite number of numbers, by measuring their distance. Well except quantum physics might get in the way, not allowing us to measure with arbitrary precision. But that would be another argument.

Another argument would perhaps be the energy required to do the computation. Maybe that relates more directly to the number of atoms in the universe, via Einstein's equation?

This is a pretty huge well except. When people talk about information that can be stored in the universe this is exactly the limitation they have in mind.
