To play devil's advocate, the strength of a model alone is not sufficient: I could say: Well, how can we be certain "gravitational waves" detected by LIGO aren't random dark matter density ripples and not GW from events we haven't correlated (n=1 on independent correlations). In other words, the dark matter model is too strong, because there is a arbitrarily parametrizable density field... Hell, there are people postulating Sagittarius A* is a very dense ball of DM and not a black hole. At that rate you can explain anything with dark matter. I have no logical or philosophical basis for this but in general when this sort of thing starts happening I start doubting the validity of a concept, not gaining confidence in it.
