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.
If you would rather have something happen over nothing happening at all than you are not against that something BY MY DEFINITION. And if you are against everything that requires resources but is not the optimal use for those resources then you must hate almost everything including yourself and all of your decisions and you should definitely be against wasting your time on arguing instead of inventing or working or volunteering or whatever. nothing as in nothing that uses those resources and not 'nothing in the universe'
