Won't dreams stay dreams?
There's literally nothing there, why go all that way? The distances are so incredibly vast. It seems like we ought to be content with staying put.

There was literally nothing there? Why go all that way? To see what was there. And then to make something there.
[Edit, because I'm rate limited: No, interstellar space is something to cross, to get to stellar space. You think the New World was rich? How about a whole solar system of untapped resources?
That's why people will try to go.]
The hypothetical riches were quite obvious: same stuff we have over here, but not owned by someone yet.
What are they hypothetical riches of outer space?
This is a question we should think about clearly and logically without resorting to stuff like "oh tally-ho the adventure!" type nonsense.
Just imagine the economic output of a civilisation a million times the size of ours.
Then we can use all of that new productivity to start working toward the next rung?
Our economy is not currently throughput limited on water or space so I don’t find this compelling.
In the past, I've challenged the "Let's colonize Mars!" people to do something that's far easier: Move to Bouvet island, now.[1]
This is a frozen uninhabited rock that is nonetheless a tropical paradise compared to Mars. It's far easier to reach, has free unlimited oxygen and water, and gets more solar radiation also for power! It's luxurious compared to the colder, dryer deserts of Mars where there's only dry rocks and near-vacuum.
If you really want to spice things up, donate $10,000 to a charity per pound of material you take to the island (what does a shelter weigh?), take 100% of your food and water with you, and never go outside without wearing full scuba gear. For "realism mode" sprinkle a small amount of radioactive powder evenly everywhere around your habitat area.
"Yay! Adventure! Honey, tell the school we're unenrolling the kids and taking them with us to this wonderful opportunity to start a new life!"
You miss the whole point. The point of becoming an interplanetary civilization is not to fill every barren rock you see (and there are plenty on Earth, and, if climate change isn't controlled, there'll soon be more). The point is to put just enough humankind on all the places we can easily reach (at that given time) so we can expand from there with in-situ resources rather than only expand from here, using only Earth resources (which WILL run out).
Some humans seem to have evolved a motivation to explore their surroundings. At first we walked, then we learned to ride animals, wheels, boats, airplanes, and, recently, spacecraft. We travel to learn both about other places as we do to learn about ourselves. Some people might feel content with our current reach, but I feel constrained.
You can't answer that from Bouvet Island, can you?
