I can think of a good reason but i'm not sure whether you're willing to buy into it.

people naturally don't think of themselves as individuals. people think of themselves as a group/society.

People recognize that under a republican US government, they're significantly more likely to go to mars and have prosperous offspring. while if they're stuck on earth, a recession and decline is waiting for them. they can't verbalize it and probably aren't even rationally aware of it, but i guess they can feel it with their heart.

of course lots of you folks are gonna immediately chime in and say "nooo i saw a youtube video that explained that it's impossible to live on mars", and honestly, you should reconsider why you're so eager to deny a topic that you've clearly not put in as much effort to think about than the people who actually do care about this project. and also, assuming it does work out; what will you do then? be ashamed of your wrong prediction? because if you're not, that means you don't stand to your prediction, and therefore the prediction is worthless. i'm not sure whether i was too direct about this and somebody perceived it as rude, but i'm tired of this feeling of being stuck. we need to think long-term again.
