Pick one:
1) You can purchase and apply your own screen protector of your own choice.
2) Apple can provide one and raise the price accordingly.
Personally, I much prefer choice #1.
Samsung does #2 and applies one at the factory; you can read numerous posts elsewhere from Samsung owners annoyed they are paying for Samsung's protector when they want to apply their own on other forums.
If you really dislike screen protectors, use a good case that covers the screen, absolutely no putting it into or taking it out of pockets anytime it would rub across the screen and make sure your hands are always clean, and you can do it; many people do just that.
