Uh, no. None of that explains the fact that the large structure of the galaxies we observe is not possible without extra mass. This has nothing to do with observational error or rounded calculations. The shape of the galaxies and their internal structures are clearly wrong. Besides, this also ignores the fact that we observe galaxies both with and without dark matter. These galaixes have very different structures that cannot arise from the same physics unless we consider dark matter.
