I don't think MOND proponents say the theory is complete, just that alternative gravitation theories is the direction that should be taken for research instead of funding futile dark matter detection projects.

Why instead of? Dark matter is, so far, the best model we have. Seems sensible to continue research in that direction.

>futile dark matter detection projects.

Why are they futile?

In the context of this article, evaluating the no-dark-matter future is probably in scope.

In general, that statement would require defense.
