It has one: there's no need to worry about finding a dark matter particle when there's no room in the standard model for one. I'm surprised how astrophysicists take for granted that such a particle will show up in a collider eventually, if they even think that far ahead.

The standard model is incomplete, we know it's incomplete, we don't expect it to be complete, and MOND doesn't fit in the standard model either. Even if you limit it to things we have observed, the standard model simply doesn't explain gravity. It doesn't explain why neutrinos have mass. It doesn't explain matter/antimatter asymmetry. We know gravity exists. We know neutrinos have mass. We know there is more matter than antimatter in the universe. These aren't remotely controversial, and the standard model either doesn't incorporate them or gets them wrong.
