Without knowing anything about MOND, this never made sense to me.

If MOND can explain away all cases where m > 0[*], it'd be a bit strange it can't explain m = 0.

If MOND can only accommodate a certain range, wouldn't that also present a problem for dark matter? If all previously known galaxies had dark matter in that range, why would every galaxy have roughly the same amount of dark matter except the one that doesn't have any?

[*] Where I guess m would be the ratio of dark to ordinary matter.

MOND can most easily explain a certain fixed value of what you call m. It has a much harder time explaining lots of different m at the same time.

They don't all have the same amount of dark matter. There's a distribution.

You were right, that a weird distribution would invite investigation.
