Just because it’s not for you doesn’t mean there aren’t people who have dreamed their whole life of doing this and would sell everything they own to pay their way if given the opportunity.
Of course there is, there are people willing to do a lot of things. At the same time the overlapping of people with the means to do it and willing to endure the conditions is extremely small...
You are attacking an argument I didn't make, my argument is that the people who possess enough to be the ones paying for a one-ticket to Mars are much less inclined to go live under those conditions. You are going to need a lot of people if you want to transform a barren planet.
