1) Consulting the world? I was unaware the moon sported a thriving ecosystem, or that the rocket would be chock full of diamonds on the return journey. I thought it was a boring dusty place. It's not like the mission is setting up a mining colony (although that would be cool).
2) Financial issues/technical issues? Fair enough.
3) Not safe? Please sign this waiver after signing your cheque. Or sign them the other way around, we're pretty relaxed about that.
4) Political issues? Given the mess the Chinese and Russians make of their own back yard, I can't see them giving a rat's ass about some dusty footprints on the moon. If they manage to get your Russian billionaire that close to the Apollo 11 landing site, then fair play, but by then it's much too late for the 'merkins to get all huffy.
5) Things will go wrong? No sh*t Sherlock. You pays your money and you takes your chance.
