This, by the way, is the thing people don’t get about space. Every time humanity takes some tiny step along the path to becoming a multiplanetary species (by which I mean “every time SpaceX does something cool”), someone comes along and complains that it seems kind of pointless. The Moon is very far away, Mars is even farther, and we have this whole big planet right here that’s already full of “uninhabitable” regions like the Sahara or the Antarctic or, uh, the entire American West. Starting there seems easier, since they already have things important elements such as “air” and “water” and “a biosphere”. Play your cards right and you won’t even need a passport, let alone a spaceship. A friend of mine even coined the slogan: “Terraform Terra first”.
But this misses the point. Yes, space colonization appeals because it’s part of the wizardly dream of innovation, of building new and exciting things, and thus has an aesthetic draw that goes beyond practical arguments. Yes, long-term we probably shouldn’t put all our civilizational eggs at the bottom of one gravity well. And yes, many humans have a Promethean (Faustian? Icarusian?) drive to expand, to explore, to see what’s beyond the horizon. All of which is a pull to space.
Now pause for a moment and think about what would actually happen if you decided to set up your terran terraforming in, say, the Owyhee Desert of southwestern Idaho. There’s a river in parts of it. It rains occasionally, and snows in the winter. Whatever techniques you were planning to generate power and conserve water on Mars would certainly work in Idaho — more efficiently, for solar, since we’re closer to the source, and with more margin of error if you can add water to the system. Plus the desert is full of exciting minerals you can mine to sell or even to extract water from! And the second you tried, the Bureau of Land Management (which owns most of the Owyhee, and indeed most of the American West) and the Environmental Protection Agency (which has opinions about mining) and the ranchers (who would also like to use that water, thank you) will come down on you like a ton of bricks.
That’s the push to space.
The dream of space colonization is partly about all the ways it would be cool to live on Mars or the Moon. But it’s also, implicitly or explicitly, a claim that it’s easier to solve enormous technical challenges (air! water! food! solar radiation!) than it is to solve societal challenges on Earth. Terraforming is hard; eunomiforming is harder.1

- Though to his credit Corcoran has a diverse portfolio: in addition to the space colonization dreams, he’s tackling the “terraform Terra” angle with an active homestead (he’s written some guides) and the “improve society somewhat” approach through more direct political engagement than I’ve ever done.
