MOND vs Darkness

.. and yet, all of the current theories which, (for the most part), explain what we see, need DM.

That's not the point....the whole matter boils down to what DM actually is and whether it exists or what we see is something else. Just because we give something a name doesn't mean we know what it is. Like I said, DM is a moniker we've stuck on something we don't really understand. We call it "dark matter", but what are we really seeing. What if it's an amplification of a quantum scale process due to the presence of so much mass...maybe the effects of higher dimensional space on spacetime, "shadow" mass, who knows.
