It wouldn't. Or to be more precise, any purpose to moving bodies would be better served with a different solution. Goal: Announce selves to greater universe.

It wouldn't. Or to be more precise, any purpose to moving bodies would be better served with a different solution. Goal: Announce selves to greater universe. Method: Occlude parent star in a way judged not natural. Dumb Solution: Destroy an astronomical amount of energy and time to reconfigure a system. Real Solution: Just build star shades. ------------ Goal: Create a way to travel easily in the system. Method: Use gravitation wells of bodies in the system. Dumb Solution: Destroy an astronomical amount of energy and time to reconfigure a system to make slingshots predictable. Real solution: Slingshots and other orbital movements are already predictable, use sails and Hohmann transfers for cheap movement, and fusion + ion / antimatter + ion drives for fast movement. ------------ Goal: Engineer a star (e.g. starlifting, nicoll dyson beam, star moving with a statite shell, etc...) Method: Use material from orbiting bodies Dumb Solution: destroy an astronomical amount of energy and time to reconfigure a system to move bodies closer to star Real Solution: Send material from bodies into desired location with mass drivers.
