If I am, so what? That is completely irrelevant to the point that space is inhospitable to human life and drastically different than setting sail to risky and unknown, far-away destinations on the earth. Nobody is going to get space-ship wrecked on an asteroid. They would be dead.
"The only difference is that early sea explorers were able to realize economic benefits incrementally."
That is far from the "only" difference and this statement is delusional if you actually believe it. I think that you've been reading too much science fiction.
