^Right. Far less energy-intensive just to go to their own asteroid belt and use solar sails or ion thrusters to redirect the courses of a few dozen large ice-bearing asteroids or protocomets to fall inward, then park them in orbit around their home planet. It'd take a few years, but it'd be comparatively easy for any spacefaring power to achieve.
