Take the human component, opinions, money, preferences, etc. out of the equation and I think you just nailed it.
There are enough omni-surface runners that have convinced me that what you say is true.
I personally buy real sheepskin slippers, and real wool or cotton fabrics to wear, eat veggies I grow myself, and have real-wood decking and fencing, is that mother nature knows best.
However, modern materials have their place, and there are just too many instances where I would defer to the newer modern high-tech "fake" stuff --- teflon, ripstock nylon, polymers, ceramics, alloys, polys, etc.
Goretex rocks! 
Whether or not "fake" has a place in racing is yet to be determined, IMHO.
Scientifically, nobody has proved anything beyond the shadow of a doubt about racing surfaces, as the fake is too new to have collected enough data, and ditto truly reliable and scientific statistics/data on all 3 surfaces. If you put together a real crack team of talented scientists who had NO conflicts of interest, and enough real data to even start a real study, I think we might get somewhere.
Anyone who says they have the answers without a bullet proof SERIES of studies (which will take a long time) is just groping in the dark, in terms of real science.
