If a scam works, it cannot be stupid...
Not for those who make the scam, but for those who putting money in it, and quick read fiction in the Mars-one website instead of doing a bit research and know this is impossible financially already for a non-government, small, non-profitable group. Even Musk dream to send people on Mars before 2030 is more realistic then Mars-one.
And then we skipping so much technological, social and ethical problems what would coming up with this plan of Mars-one. Besides that nobody really co-operating with Mars-one, says already enough that the plan is basically dead.
