Isn’t Antarctica just Mars-lite? Do you think a mere treaty is hampering settlement there? That’s where my mind goes when people talk about colonizing another planet.
These people are incredibly stupid. They somehow think colonizing mars is easier than regulating the environment here on earth, somehow think elon as dictator is better than any earth government, are interested in putting undertested and sketchy implants into their brain even without a proposed use case, and seem to think that the only reason we don't regularly visit mars is because we don't have a big enough rocket, as if easy access to tons of powdered rust is economically useful.
Flying to another planet on a rocket is obviously very different, the goal is way more interesting than the challenge of living in a hostile environment. Even if it's ultimately a useless exercise for humanity.
