No, they should be left free to do what they want. Because that's the principle by which people such as Elon Musk have the resources necessary to revolutionize transportation, internet service (they are working on geosynchronous satellites that promise to provide fast, affordable internet access), space travel, etc. Do I really need to explain how the introduction of things such as the Hyperloop, electric cars, a global wireless internet service, backing up humanity on Mars provides a benefit to everyone, including "working people?" How about the overview effect? By making it much cheaper to access space with BFR, more people will experience this. And that might reduce the level of support for war and other calamitous behavior: https://en.wikipedia.org/wiki/Overview_effect https://en.wikipedia.org/wiki/Overview_effect And yes, I know people will tell you that all of the above is only affordable by wealthy people. But that's not how technology works. Early adopters (rich tech people) pay lots, offsetting R&D costs, and each successive wave of the technology is cheaper, faster, better. For example, the original iPhone was expensive. But lots of people have iPhones today, each of which is far more capable than the original model.
