I hoped you might see the analogy, but apparently I was mistaken. So let me translate: The fact that certain factors are always present does not prevent us from isolating their impact.

The part that you keep ignoring, is that their (diffraction) impact is different for the two cases we discuss.

After a lot of dancing, you are trying to change your statement to something like this: If we can perfectly scale a lens and consider the geometric optics theory only, the projected images scale by the same factor, as well. Duh! Do you really think that we are still discussing whether if you can shrink something, it shrinks?
