As we all know pinhole is not about sharpness, nor I am suggesting we
strive
for it. Having said that, it is actually possible to make poinhole images
that under certain conditions could be undistinguishable from glass lens

Diffraction cannot be avoided, it's the way light behaves when going

The
best optics
are said to be 'diffraction limited' which
a glass of water with a straw inside is a simple example.
you see the straw bent but it is not.
thats what happen with light when it changes the medium it is travelling
(from air to water or through the glass, example). I am not sure about
what happens with pinhole, once there is no medium
