My opinion is the Mahanidana sutta is one sutta distinct from scores of others on the subject. Plus it is in the Digha Nikaya, which appears to be precursor to the Mahayana Suttas and thus doubtful if spoken by the Buddha. If so, it was spoken to Ananda, who was unenlightened and not ready for stream entry.
Also, discerning reality is something to be considered. For example, when we look at our body with our eyes, both actually or in a mirror, we are not actually experiencing the body thus there is no existence of the body. When we look at our body, we are merely experiencing a sight via the eye and eye consciousness.
However, in meditation, when consciousness descends into the body itself, then the mind directly experiences the body via the body sense organ and body consciousness. For example, in the first satipatthana, Buddha uses the phrase "experiencing all bodies" or "experiencing the whole body". The mind is the same in cittanupassana. Unless consciousness descends or enters within the body & mind itself, there is no direct experience or existence of the body-mind.
For most human beings, the body is something seen via the eye and the mind something heard via the ear. As such, there is no arising of nama-rupa.
Just my ecsoteric opinion, which I cannot spell.
For your consideration,
