Life has survived. but many species went extinct. I'm a little selfish. I want MY species to survive.
Frontiers are good for us. I don't want tax money to pay for punching holes in the frontier but I would like to have our species be (mostly) free to go out and reach for that frontier.
One thing not mentioned here (yet) is how much more efficient we tool users could be when we're outside the bounds of our fragile ecosystem. What if we could strip-mine an asteroid using methods that would be cheap but possibly really bad to use on Earth. Also we could use engines outside of Earth's atmosphere which (if used in Earth's atmosphere) would be bad for Earth but for moving about the solar system these engines might be reasonable.
If we have to use rockets from Earth to transport every material the extra-terrestrial humans would need, we'd have a very limited existence off Earth. But if we can use human ingenuity and make what we need from materials we find off-Earth, I bet we can do much better than is obvious to us Earthbound people.
So far all of our experience off-planet has been supported entirely from materials brought from Earth. The only exception I can think of is power from the Sun. We need to change the ratio. We need to have it that most of the matter consumed and used off-Earth comes from off-Earth. That will take some ingenuity.
I like it.
