Seems like the material human cost of space travel never even occurs to them. The poor indigenous people who mine the precious metals and iron etc. that make the spacecraft, the massive costs of feeding and housing all the engineers and scientists working on Musk's futile vanity project -- none of that is even on their radar. They reason that because SpaceX is more efficient and cost effective than Boeing/Lockheed/Northrop that Elon deserves all the praise in the world. In their eyes, Elon is "selflessly" dedicating his time and money to "saving" the human race by making it multi-planetary. The OP calls anti-Elon people "cultural authoritarians" fueled by "billionaire-hate" who want us to be "imprisoned on this planet forever".

Imprisoned on this planet???????

Are you fucking kidding me? Every good thing a human being could possiby want is on this planet. What's on the moon? Grey rocks. What's on Mars? Red dust. There's nothing out there. There's really nothing in space worth having. If you're not happy on earth, that's not a problem with earth, that's a problem with you (or the social or economic structure around you). Moving to a new planet is not going to solve your self esteem problems. That whole thread is just full of so much bullshit.
