How can an individual with Superman like powers best harvest asteroids?

In a story I am writing there is a being with Superman level strength, flight, the ability to produce lasers, and survive in space. He has decided to solve the mineral crisis by finding and grabbing an asteroid and taking it back to earth so that it can be used to build lots of cool things and green tech.

They have the backing of an eccentric billionaire, and moderate political will in support of them, and modern earth technology.

How would they best, with brutal physical strength, flight, and lasers get that mineral wealth from space to earth?

Some constraints- they can, essentially forever, produce 200 megawatts of power for use in flight or lasers.

Their flight doesn't require notable reaction mass.

They are durable enough to survive space and high accelerations essentially forever, and air isn't a concern.

They don't have magical forcefields to make asteroids stay together or behave.

Ideally, humanity will be functional as a civilization by the end, with no world ending impacts. Props to any answer which involves less loss of human life, or none.

To summarize- how could a being with 200MW of power eternal best harvest asteroids?

Edit. As JBH noted, science based questions don't have to have fully plausible scientific questions, the answers have to be plausible. That said, you can replace the superman with a 200MW fusion spaceship if you prefer with lasers and flight.
