It is private resources and a relatively low amount as well so this is baarely applicable here. It is obviously not the optimal use of resources (because we probably can't even calculate the absolute optimal use of those resources) but if they are doing anything even slightly positive we should be for it and most will argue that this is a highly valuable endeavour for humanity (even if we only account the amount of useful tech that will be invented/improved during the course of this mission).
Huh? How is this relevant? The question isn't is it better use of the resources than some possible options, the relevant question is whether this is the best use. No one disagrees that this is a good use compared to many options. But if this isn't the best use, then yes, I'm against it, in the sense that I'd prefer it to go elsewhere.
