Why nobody bought the moon yet?
Did you ever ask yourself why no country owns the moon? Why did nobody decide to buy it yet and make money on it? Well, because you can't do anything about it that will bring you money.
I once had a late evening conversation with one of my relatives about how Elon Musk is trying to fly to Mars and build a colony over there. And I was convinced that we need to be able to fly to different planets and universes in order to develop as a human species further. New resources, more space, new planets, new environments, etc. But then, my relative said one thing that stuck with me for a couple of years and I couldn't find an answer to it until now: "We won't leave planet anytime soon because there are plenty of resources here."
This idea stuck with me because I could not find a good answer to that comment until now. We as human beings start learning when things are going bad. Hard times is what makes us smarter and eventually help us evolve. Hard times is what we call progress. This is a process of life that can't be changed. From the times of caveman when we taught ourselves to build weapons for hunting and learn to kill mammoths in groups, until now when we learn new skills such as coding so we could keep with the modern world. So unless things go very bad, we won't leave this planet anytime soon. It is only for people like Musk who believe in bigger things.
But there are 2 ways how to convince the planet (big guys with money) to start working on a different kind of future rather than staying on planet earth. One is to deplete all resources so we can start acting, or convince wealthy people that they could make money out of it. And this idea of making money came to me from a letter Michael Faraday wrote to Prime Minister William Gladstone, on the usefulness of electricity. The letter had this: "Why, sir, there is every possibility that you will soon be able to tax it!"
The problem we currently face is that we are too blinded by the microeconomics that happens on a day to day basis and we don't see the big picture. There are simply too many things to do in a day in order to think about the future. And it is a job that not anyone can do it, but only people who are able to step out of the crowd.
If you could show a proof that, for example, on Mars or any other planet are resources that can be extracted and you could have enormous returns on them, then the big guys will start moving their capitals into space. The movie "Avatar" by James Cameron shows this idea in practice very well. Once there is a chance to make money, people will fly anywhere.
