Beyond retarded idea. Keeping a planet in one piece and instead terraforming it to specific resource needs (forest worlds, ocean worlds, etc.) provides a million times more value over a long period than just harvesting it for minerals. The latter can already be done with gas giants and asteroids.

Not to mention suface space on an actual planet is like 0.00000000000000000001% of the mass in the universe, every planet is a valuable real estate for people to actually live on. Even inner/outer planets can be adjusted in their orbit.
