2. It is much easier, safer, and cheaper to send rockets into space to mine resources than to scan, get a permit, build a perimeter, plan your mining facility, handle environmental issues and finally dig for resources.
Asteroids have collided with each other since eons and thus any lose dirt was gone - only dense metals.
3. More energy.
Fossil Fuels are not feasable in the long run. Nuclear power obtained from mining asteroids for uranium is the future. Assuming nuclear fusion reactors were finally achieved, Hydrogen is the single most abundant element in space.
Not to mention taht Neptune has a moon loaded with methane that we too can use for fuels
With so much energy, electricity would be too cheap to even count
