Interesting perspective! I'm reminded of Hesse's Siddhartha: "I can think, I can wait, I can fast". Imagine how many of our external problems could be solved if we were all better at these.
While I don't disagree that solving inner problems is valuable, I do think it's harder to imagine doing that at a civilizational scale without external forces changing the playing field. In other words, I'm not confident that if we just stopped technological progress and thought about it really hard, that we could work out our problems on a species-wide level.
As far as going to Mars is concerned, one thing I'm scared of for humanity is resource scarcity. Much of our external conflict seems to be strongly correlated with competing over finite resources and I see Mars as a resource play.
I agree, though, that a lot of us (myself included) don't know what to do with all this freedom. But I'm hopeful that we'll become wiser as culture catches up with technological change and better equips us for the coming world.
