Your camera has far too few pixels for your lens, as evidenced by the heavy aliasing.

You don't know what you are talking about.

You are the blind person here.  I see everything you see in your image, and more; I see well enough to see what is wrong with it;  the edges are in the wrong place.  Any capture that can result in a white pixel next to a black pixel can not possibly render edges consistently, or in the right place.

A filtered (or properly sampled) image's center weight of an edge is much more accurate and consistent than one that is undersampled and aliased.  The fact that you don't notice how inconsistent and incorrect the location of edges are in your image, and prefer crispness as an end in itself, is not something to brag about.
