Wouldn't I be able to patent the idea of landing a rocket using a reverse launch process and stabilization fins and jets, even if I'm not even capable of landing a stone? If the implementation doesn't matter than I just locked everyone else out of landing rockets for decades.
The idea is worth something but so is the implementation because ideas are generic and the more specific you make them, the more you actually define an implementation, in the physical world at least.
