You're quite right. But in the past pioneers didn't expect me to pay for their adventures through taxation. I'm all for colonizing mars when we have the technology to do so, but we don't and we won't for hundreds of years. There's no reason to send people there now.
>Last time I checked SpaceX was a private company, either profitable already, or on track to become so pretty soon.
SpaceX is a private company, sure, but so is Boeing. Much of the funding for their current activities comes from NASA. The easiest business in the world to be profitable in is government contracting.
>And even if you were talking about the NASA mission, I'm still all for it, no matter what Zombie Ayn Rand is mumbling in the basement.
Great. Why don't you pay for it then, and leave the rest of us out? There isn't any reason to send people to Mars, and the effort will cost over a trillion. It's hard to imagine a use for that money that wouldn't be more productive.
