3D is limited by the constraints of biology, geometry, and the physical environment. The unavoidable negative aspects - skin defects, unmanaged hair, unfavorable lighting, the slighest deviation in body proportions - must be managed in some way, always with compromise.
2D, on the other hand, can be absolutely anything. It is exactly the way the eyes see - a matrix of red, green, and blue light in varying quantities - and is as close as we can get to a direct transfer of visual information into the brain.
Limited only by the skillful and cultural means by which arbitrary arrays of pixels can be constructed, generations of otaku have cultivated highly refined ways to communicate the ideals of cuteness, purity, femininity, and affection, plus whatever auxiliary traits one might desire. And as it turns out, we respond more readily to certain body proportions, head shapes, and other visual cues, than are possible within the confines of 3D. This is to say nothing of personality, on which the freedom of writing acts similarly to transcend the biological and social limitations of the real thing.
Being constantly delighted by this ultra-fine, ultra-perfect representation, we become acclimated to it, and thereby shed the burden of unconscious compromise which inevitably accompanies the real-and-therefore-flawed. When you've slept your whole life in a cushioned bed under fine covers, you become repulsed at sleeping on the dirt as our ancestors did.
