think of it this way: you go there, work for a company, in a spare time, you find gold, raise capital to start mining it, got rich, build a huge house with swimming pools, and all the rich attributes, but on Mars.
Mars will be colonized with great mixture of science and initiative people. Your kids will grew up in this environment, they'll receive best education and endless room for possibilities.
Sure buddy. You will be able to prospect for and mine gold in your spare time after your one-way trip to Mars, including building all of the equipment you need, or having it sent over by rocket. And you'll be able to own land there too, because homestead laws and stuff will definitely carry over.
If you are already rich on Earth, you don't need to take risks that insane to try. In other words, nobody who can afford a ticket to Mars will pay for one.
Surely elon will allow lots of other people to get rich, instead of just capturing any possible value for himself, since he would literally be a god emperor.
There are no rules on mars, except the ones that the people who could simply push you out the airlock make. Look how elon treats his workers and you will understand how a mars colony with his backing will look, except even worse.
