Seems mutual. It took knowledge to exploit coal, oil, etc., but greater energy usage created an explosion of wealth/knowledge (I.e., people could specialize in knowledge rather than having to farm/hunt by hand, which is energy-inefficient.)
Easy low gravity is an absolutely gigantic benefit for Mars, the Moon, and space in general. The challenges of living there will (a) cost a huge amount in the short term; and (b) produce trillion dollar industries over the long term.
Do I know this to be true? No. But that's why it's exploration, not betting on certainties. Unknown unknowns dominate. My guess is that betting on Mars is a 100x bet... with a significant probability of 0x outcome.
Just one example: think about the challenges for chemists & synthetic biologies & materials scientists on Mars. They're going to be asked - indeed it will be imperative - to solve a whole lot of problems they would never have been asked to solve on Earth.
