These 'reasons' primarily apply to street -vs- organ shoes; and offer no particular advantage over good 'ole socks:
- Are clean, and keep the pedals clean and clear of dirt, sand, salt (I live in snow country), and other contaminants. I NEVER wear them outside.
Same goes for socks: They are clean, clear of dirt, sand and salt; and they are seldom worn outside in snow country. 
- Have soles which allow one to feel the pedals through the sole. With wear, the sole molds to the foot and become more comfortable over time.
Pretty much the same attributes could be applied to socks. 
- Are the right width to fit between the pedals. I've found it's hard to find street shoes wide enough for my feet which will fit between the pedals--allowing me to play only one note at a time without contorting my ankles to get the right angle.
Socks are even more accomodating in that regard. 
- Prevent the obvious--odor!
Dunno how that one got in there, but I suspect that socks would be the clear winners on that point.
- They have a heel just tall enough so I don't have to overflex my foot when playing with the heel - a real hazard.
That's an interesting consideration; but I am skeptical of the real hazard aspect of the endeavour. While the achilles tendon (tendo calcanneus) tends to be somewhat resistant to yielding to increased dorsiflexion, with a little persistance it can be achieved; even for old folk. The accepted approach for achieving increased dorsiflexion, is to do knee-bend squats while keeping your feet flat on the floor. Wearing high-heeled organ boots, is unlikely to augment this kind of flexion, to the point that you become dependent upon organ shoes.
'Course, from the outset, this thread has failed to address the matter of where you wear what! 
Most of us might wear something entirely different at home, than when out in public. I tend to remain convinced that wearing organ shoes in public, rather than socks, is more a matter of public presentation than an artistic consideration.
Like . . . . for all of you organ-shoe advocates; what do you actually wear at home, when you want to relax and just enjoy yourself ??
As a sidebar, cultural differences tend to be enormous. We recently enjoyed, as a guest in our home, a young medical doctor from India. As he entered our home, he immediately removed his shoes. No big deal there. But he then he continued on to remove his sox, parading around the house for the rest of the day, barefooted in a business suit ! From the very Beginning, God figured that covering up the human body was a really good idea!
As long as you only have to wear sox . . . .
