Because it just so happens that this is where we are.

Earth can only sustain so many people, and since we do not currently have a viable way to get off this earth and/or to terraform other planets (hell, we can't even agree on a common plug to use for household appliances) it looks like it will remain that way for a while.

Yah, but it will also take a while to reach the limit of the earth, by that point we will hopefully be able to expand off of the earth.

Um, we've left the earth already. The only reason why we don't continue to do so is that it isn't cost-effective -- which means that we have another resource-allocation problem rather than some mysterious insurmountable challenge.
