They're holding back on FaceID to offer it as a feature later on. Thats the only reason as to why they would hold off on it. If they truly felt it wasn't necessary, then we wouldn't have it on the iPhone either. Their excuses are the same as when they didn't have iPhones with 3G or multitasking, they simply don't hold up to any part of logic.
No touchscreen on Macs is because they know they can sell iPads that have a touch screen in addition to a laptop that doesn't. Having a touch screen wouldn't hurt the laptops at all, and can be disabled if someone truly hates it as well.
