Moon has no atmosphere, so all required Δv can be applied at launching point. It's much much harder to land on Moon, than to launch from Moon.

Lunar escape velocity is still pretty high. 2.4km/s compared to earth’s 11.2km/s.

However, there is a gun that can fire projectiles at 8km/s so it’s possible.

Unlike on earth, a space elevator is actually feasible on the Moon with current technology.

Exactly. The moon has a gravity well, and while it's a sixth of Earth's, it would still take a lot of energy.

Plus, there's the public relations of mining the moon, versus mining asteroids.

Perfect use for a system like SpinLaunch: - no fuel, just solar energy - the Moon always faces the Earth with the same side - no air to create drag - no need for huge burts of energy - a block of minerals does not mind extreme g-forces
