The whole idea of a DSLR is that you have an optical viewfinder so that you can actually see what you taking a shot of, rather than watching some time delayed low resolution bastardised version of reality, usually at arms length. It is not that hard to focus accurately with the existing system or even (god forbid) manually
I'm sorry, you're just wrong. First of all, the viewfinders are not really that great for checking focus, especially if your vision is anything but perfect. Even then a lot of people buy focusing screens and viewfinder enlargers just to have a better chance at nailing the focus. Modern DSLR's are made under the assumption that everyone uses AF, that AF works perfectly and people only use the viewfinder for general composition and not for checking exact focus.
Secondly, sometimes you are in a position where you cannot put your face right behind the camera, but with live view, you can still see the composition (and focus, if you have peaking). Peaking is a very useful tool and if its implementation doesn't cost an arm and a leg, I see no reason why it isn't included.
