He may not be able to afford a Saturn V, but that's not what he plans to use, he plans to use multi-launch mission using reusable Falcon 9 Heavy. Everything he has done this far suggests he is able to build it. I am not saying he can't fail, but at this point it takes too many unsupported and ill-informed assumptions to just say he isn't going to do it.
This is getting a little bit old to be honest. First it was the main engine. Musk isn't going to develop and/or build one. Look at how much NASA spent developing F1! There is no bussiness case for that! Then it was Falcon and reaching orbit. Musk isn't going to develop and build one! At best it's going to end with huge fireball! Look at how NASA spent on putting things into orbit! Musk isn't going to deliver cargo to ISS! Look at how much NASA spent developing rendezvous and docking technology! He can't afford that or build that!. Give me a break.
It was never guaranteed that was going to succeed and it still isn't. And I understand that you people may not be his fans. But it would be great if you could, for once, learn the difference between you not wishing that he succeeds and him actually not having chance.
