Re: Don't forget the fate of early Earth colonists
"Mars has an abundance of what is the single most pressured resource on Earth: land."
That is complete bollocks that can be transformed into absolute truth by simply addìng the word 'habitable'. There is plenty of land available on earth in Sahara desert, Antarctica, siberian and Canadian far north, himalayan plateaus. All of which are much more habitable and much more easily accessible than mars.
Poor people can't get to Mars, and if earth's governments want to find a place to export troublesome locals to, there are plenty of places to send them to
