Oh we do agree there, control is more practical. I don't personally think alignment is even possible.
The problem with control is that it will fail at scale. We can't control something that is actually smarter than us, if AI (LLMs or otherwise) get there.
Chimps wouldn't last long trying to contains humans. Maybe for a while they'd keep us scared, but we would come up with ways to escape that the chimp could never have considered.
