Because 79% of us are mortals and can't afford to keep buying a replacement. Also it helps preserve some resell value if the phone has lived in a case for most of its life. My current cheapo Moto G3 lives in a case. The first one I bought fell out of my pocket in a car park and that killed it....so guess what, I bought a cheap case to protect my new one. > What's the point to pay top dollar for a beautiful screen if you cover it with a cheap cover? Well, when you need to, you open the cover then gaze upon your beautiful screen ;)
