I care about poverty and war and politics and curing cancer, of course, but that's not all I think about 100% of the time. I can only speak so definitely for myself, but I'd be willing to bet that you don't either. You could apply your logic to all sorts of things, and look down your nose at having a drink with friends, or walks along the beach, or painting, or playing the piano. Why play with your kids, there are diseases to be cured, come on! None of really live our lives like that.

Actually, my main problem with this particular Kickstarter is the blatant copyright infringement, which Kickstarter usually takes down.
