If they can't demonstrate that they can launch a crew, convey them to their destination, and provide them with some form of functional shelter then they will never get off the ground.
How so? Who's going to stop them?
I think the real issue here is screening 1058 suicidal or terminal maniacs with a death wish out of 200k suicidal or terminal maniacs with an even greater death wish, and hope that somehow out of those a useful crew will be able to run a friggin' spaceship. To Mars. And build the foundations of a colony. On Mars.
An astronaut is usually a pilot, AND a glorified lab manager, AND an engineer, AND physically superfit, AND possesses iron willpower, and his balls are probably made of some badass titanium alloy. He/she is NOT suicidal and, though risks are understood, made a brave choice and is backed by thousands of professionals on the ground. He/she is not a telephone sanitizer backed by some soap opera script writer and his CEO.
There are many, many, many things that can go wrong here: and I am not talking technicalia, I am talking about human behaviour and attitude: people become obscene, detached, depressed, sarcastic, suicidal and even aggressive in reality shows on EARTH. And the masterminds behind this endeavour are okay in sending I-am-cool-with-it-being-a-one-way-trip reality show material to Mars?
The sad part is that I am pretty sure that it is going to actually happen, and it might end up badly not because of a hardware failure or similar, but because of human moronity: this sound more like a "put some humans in an airtight tin-can on Mars, and watch them perish on TV" (or even "better", watch them kill each other)
