There’s a big gap between knowing that an asteroid contains a lot of valuable metal and extracting that metal, let alone bringing it back to Earth. Of course, you could use it to build things in space which you wouldn’t have to lift out of a gravity well, and that is probably the most compelling use case for asteroid mining, in reality.
