Clones are the same genetics but not the same individuals. They are identical twins in that the share the same genes; however, they are not identical down to the hair. If we relied on reproduction the way "God" intended it than we would not have artificial insemination, fertility treatments and numerous other advances that allow childless couples to have children. I don't know that "God" has a place in science, because if we did what was indicated by the bible science would not exist.
I think cloning has a great potential in being used for organs which would reduce donor rejection and reduce the number of people who die everyday due to not enough organs being available. Cloning has a place; however, making the play things of the wealthy is not it.
With horses, mammoths and other "pets" I don't think its of use. As others have said there is more to success than genetics. I also think that part of the reason these horses are amazing is that they are not like every other horse out there. If every horse was a High Brow Cat than he would not be special. Lets face it half the fun of breeding for folks is finding out how good you can get. Knowing the outcome sort of salts that pot.
