> The Bullet Cluster is a particular instance where we can actually "see" the dark matter flying around, in a way MOND couldn't hope to explain This is not correct. In fact, LCDM can't even explain the Bullet Cluster [1]. The evidence is not so favourable to LCDM over MOND [2] when taken as a whole. More recent observations on wide binary stars disfavour MOND more strongly, but the classic reasons you cite are not valid reasons.
