I agree with you wholeheartedly that phone ordering is the best method, and I use it myself most of the time. It's always been the best method except during the busiest takeout periods at the busiest restaurants.
I just wanted to point out one nitpick, when you mentioned this: "Even if you're deaf or blind, you can order pizza over the phone without issue."
That is true, but that doesn't mean that online ordering systems cannot help people with disabilities. My brother does not have to live alone, but if he did, he is mute and has trouble using a speaking device. An app would be far easier for him than a phone call. In other words, accessibility requires both systems, not one or the other.
