It's the same thing. You can look every subsystem as a whole, or only the "whole system", it's motion would be the same.
For example, you may cut the Moon into 777 pieces in your calculation and still the orbit must be the same.
Also we're assuming an infinite number of balls?
Yes, we do. Here in this construction. (Maybe I should call it Kristan's complex ).
I don't think - no, I am quite sure in fact! - that nothing like this lives in the real world. It's just a problem inside the abstract Newtonian world.
It would have the resultant force to the right, and it would be great, correct?
Correct. In the finite case, it's all okay.
