Incredible strawman you've constructed there, Truth In Vacuum.
As opposed to the Disney-esque fantasy of a very nearby planet just brimming over with resources that you've swallowed?? Or the quasi religious nonsense you Space Nutters repeat about space?
Some of you have strange ideas about how wonderful the early American colonies were.
Jamestown is considered the first permanent English colony in America. Of three previous attempts, two were abandoned and one just disappeared. There were about 500 Jamestown colonists at the beginning of winter 1609–1610. There were only 60 people still alive when the spring arrived.
While Jamestown is possibly the worst example, many of the first colonies were simply abandoned. Disease, starvation, and massacre by Indians were common problems. Just getting there was a difficult journey taking many weeks and was generally a one way trip. If you changed your mind, the next resupply ship might not arrive for months.
And yet, they were able to breathe the air, the gravity kept their tools where they put them and didn't make their bones dissolve, they have food in the water, wind was free motive power, they could use the stuff there since it's the same planet.
And do all that by essentially carving trees. Here we are with magical 3D printers and a very nearby planet and we've done what so far?
Oh yeah. Bullshit, that's what. You have strange ideas about how wonderful a dead rock millions of miles away will be.
You're not going anywhere. I'm not going anywhere. Elon Musk is going nowhere. Neither are your children. Evolution is still happening. In a million years there won't be a Humanity left to care about it either way.
