Disabled people exist, even temporarily so (e.g. pregnant with a craving, broken ankle and can't drive, etc)!
Also, sometimes some meals are arguably not worth the labor of cooking. Making proper pho takes at least a whole day. Pad Thai really doesn't function without the kind of intense heat of specific equipment. Etc etc.
