He's not trying to colonize mars, he's trying to get power and wealth and for you to like him. Nothing irks this man more than someone who doubts he is a saviour. It is reasonable to demand we fix the planet we currently inhabit, rather than believe a ketamine-addict that the better solution is to just let it go to hell and move on.
If he wants power, wealth and fans then he could retire already because that would be mission accomplished. It seems that there is some other motivation.
