Your response is totally logical. I agree with a lot of the things you are saying.
My sentiment is that although we are several, several years away from a "magic bullet" as in a instant cure to the deficient gene that induces MPB, we are on the brink of a solution that has the potential to be just as effective. With today's FUE technique by some accomplished surgeons, if there is a way to produce or "cloone" healthy, dht free hair follicles, that is as good as a cure or close enough to it in my book. The sheer fact that their is no "donor anxiety" per se will transform the transplant industry from a skeptical business to the norm. If there is no scarring, no "donor anxiety," and you're at the hands of a skilled surgeon, there is certainly scarce reasons to not have a full head of hair.
I also am hoping that if replicel's technique proves to be effective at yielding permanent hair that will be nothing short of amazing even if it doesn't yield perfect density. The density lacking can be filled in with a Fue transplant thus requiring far fewer grafts than otherwise.
Obviously this is a lot of wishful thinking however in short, if there is simply a way to eliminate "donor anxiety" whether it be through histogen, cloning, hair duplication (autocloining), or replicel the results are really limitless.
