Even if you don't enjoy the science/exploration angle, asteroid mining should be incredibly good for human needs.
Any metal you can think of exists in phenomenal abundance there, and should be able to be exploited at minimal cost in the long run. Having huge supplies of cheap platinum, gold, nickel, cobalt etc would be extremely good for humanity. It also means we don't need to have dirty and ugly mines on earth.
There is also the military angle. If the west lets China control orbit, we're in big trouble.
Asteroid mining is wildly uneconomical. There is no material to be found in large quantities on any asteroid in the solar system whose value justifies the development and installation costs of the infrastructure needed to get that material back to Earth.
If you're building a megastructure in space, that's a different story. But please understand that mining gold or platinum from asteroids, at (literally) astronomical cost, will not do anything to advance the state of life on Earth except, at best, reduce the price of gold and platinum, which are not societal bottlenecks.
