The problem, which I don't think Musk sees clearly, is that the outcome of this war has larger implications than just the fate of Ukraine. Other authoritarian nations, including China, are observing with keen interest how the conflict pans out. These nations, like Russia, follow a behavioral pattern of exploiting perceived weakness. An unlikely nuclear war avoided today at the cost of letting Russia win does significantly increase the risk of world war and thus nuclear war 7-15 years down the road.
