If you want to go, fine. I'll be happy to watch about your exploits. I really do think this will make for excellent TV.
But not wanting to go to a desolate hell scape is totally the reasonable response. Not having the basic elements of humankind my ass. Are you currently exploring all the wonders of Earth? Have you hiked the Pacific Crest Trail? Have you pushed yourself to run a 100 mile ultra marathon? Have you gone to the resource lacking nations of Earth to help build wells? Are you currently pushing the boundaries of science, literature, art? If you're not already doing all this stuff on earth, don't be sitting there acting all highfalutin just because you fetishize space exploration and think that by doing this one nightmarish thing, that this makes you better than all the people accomplishing extraordinary things right here on Earth.
Don't be that guy who doesn't want to do stuff simply because other people have done it before you. YOU still haven't done it. It's like when people stop liking a band because it becomes too mainstream. ugh.
