How is there so much sci-fi wishful thinking so pervasive here? How do you even imagine that any technology could safely move an asteroid to LEO every few years (and probably have it crash into the Earth a few years after that)? Nevermind a technology that we would develop in the next 100-500 years? I would be willing to bet that SpaceX will be long gone as a company before the first successful (cash-flow positive) asteroid mining operations will begin long in our future. And that it will barely be a memory by the time we start bringing asteroids closer to the earth to mine them, if that ever happens. They will of course have made some serious contributions to this future, but this is waaaaay beyond anything we'll see in our lifetimes, and companies just don't tend to live that long.
