Riot has stated in the past that they will not remove creepblock because it would make them feel nonexistent and uninteractive in the game. And that makes sense, and I agree with it.
However in its current state, creepblock is completely unpredictable. There is no way to meaningfully manage that aspect of the game because it's an intangible, uncontrollable occurrence that cannot even be predicted or avoided if it could. If riot wants to assert that creepblock is good because it makes the minions feel "real", then it actually has to do that. Right now minions don't feel real at all. Most of the time I can't even stand near my wave because I have no idea where I'm going to path if I walk up to kill a minion.
Final point: for something to feel real, it has to interact and behave in a predictable, controllable way. It has to obey some sort of law of physics. That is a requirement for things in real life, so it has to be the same way in game. When a champion ability doesn't behave exactly the way it's supposed to, it's a problem and the bug gets fixed (or at least it's supposed to). Minion pathing needs the same treatment.
