Sometimes you gotta be wrong before you get it right.
I mean, Newtonian mechanics are "wrong" but served us well at some scales for a while, and that it observationally failed in others led us to relativity. Even "relativity" took iterative steps, from Poincaré's Lorentz invariant theory (or even earlier with Galilean relativity) all the way to GR via special/restricted relativity, the latter name having been retconned because it's only valid in restricted special cases and fails to unify generally. And we know GR fails to unify with quantum mechanics, so one of them (or both) gotta give.
So even if something as MOND were "wrong" and known to be wrong (definitely so), there's still value in experimenting with it to get a better understanding of things. That's just how things work.
I disagree: some experiments are just not worth our time. I wrote about such a situation three years ago:

My view is that it applies here as well.
