I wasn't attempting to refute dark matter as a particle or come off as a MOND supporter, I just wanted the poster to provide more info about the knowns vs unknowns when responding to the question.

This is great info, exactly what I was looking for. Thanks for the follow up!

This answer is making some unstated assumptions about theoretical dark matter. I think for clarity it would be helpful to write out those assumptions here. Particle nature, certain mass range etc.

Dark matter has never been directly observed, to my knowledge there isn't even strong evidence of where its located. So the certainty of statements like "dark matter has no coherent motion" I think needs some caveats.
