This is why the prospect of bazinga brains colonizing space is so laughable. An astronaut is basically if you roll together hardships of polar scientist, ocean oil rig worker, submariner, and underwater welder into one, and throw them into an environment that are even more inherently hostile to humanity more than all of those professions combined. For one those people only need to exercise to stay fit, not because their wouldn't literally withers because there's no gravity to hold your muscles together.

Sci-fi nerds everywhere are so high on settler fantasy that they thoughtlessly applies it to space. They're unaware that real life colonizers had it so easy because they're conquering lands that have been inhabited by people for centuries before their arrival. They came to lands where prime farming ground have been well known, where the local dangers have been catalogued, where the water sources have been charted, and the best crops for the local condition have been grown. Obviously none of those would be in space, it would be like if the settlers instead of colonizing fertile ground, instead have to settle the inside of fucking active volcano.

Everything beyond the karman line is not a "virgin" ground for us to exploit, but it's a massive expanse of nature completely alien to life from this planet with its own unknowable history that we must respect. Except that capitalist have as much respect of space as they have of anything else, which is why just like capitalism itself the commercialization of space is doomed to fail.
