I said there is one advantage MOND has in terms of parsimony. It may not be a decisive advantage, but it is an advantage.

It's not an advantage at all. Parsimony would mean not having to postulate as many new entities. MOND postulates one new entity; so does dark matter.
This is a weird argument. 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.
