Humans have been interested in space across all cultures for as far back as we have written history. It's only natural for people to want to explore areas they're interested in and haven't gone to before.
Going from Europe to America made you rich.
If you think this then you need to read a history book. Early settlers to America had very few supplies and entire settlements died of starvation after eating even their clothes. In theory bitcoin shouldn't have made it this far and was stupid to even try, yet here we are with the best money ever created.
Get a better theory, bitcoin was inevitable before Satoshi was even born.

How did you come to that conclusion? We've got reusable rockets, probes that have left the solar system, retrieved samples from an asteroid, and had people spend over a year in space already. There are many companies building different models of next-generation space stations and lunar landers.
It's nowhere close to the leap required to get to bitcoin from ancient Rome. Given all the technology we provably have and the tech we're confident will be available in just the next 5 years, what major barriers do you think will prevent us from having permanent settlements off-Earth?
