I agree with this. I've never climbed half dome. But it seems to me that the cables are creating a problem that they are trying to remedy with permits and regulations. I think that it's better to just remove the cables and return half dome to as natural a state as possible. Let people's survival instincts regulate the number of people who climb HD.
