A mixture out of: It can't look any better (depending on conditions), unrealistic expectations and user skill deficiencies. The moon is a rock in direct sunlight - ISO 100, f/11 and 1/100 of a second is the rule of thumb to expose that correctly (looney 11 rule)...

f/11 would be a bad idea for someone seeking the max sharpness.

Not with this kind of subject.

It is, because diffraction starts to become a real issue with high mp sensors. F8, or even f5.6 will produce sharper results with high quality lenses.

That wrongly assumes that there is anything that would have pixel level sharpness - but the moon with the 10+km of distorted and possibly dirty air between you and the subject will never exhibit such pixel level sharpness. If you were to shoot a resolution chart at 1 meter distance then I fully agree but for the moon - never!
