- You assume that we give up on Earth if we ever leave for another planet? I see that as one of the biggest successes of our species should we accomplish it. Becoming an interstellar species would be a huge achievement.
So, yes, you can feel free to be idealistic about the how -- putting someone on the Moon is the ultimate ideal fulfilled -- but you can't be idealistic about the why. The way we're going now, space travel will be a necessity, not a luxury. That's why I see it as a failure.
- why can't we take care of Earth AND travel the stars?
Because we're not doing the former, so we'll have to do the latter.
