You are arguing in bad faith. You are also creating a straw man argument attempting to rubbish a feature that works acceptably well in 99% other use cases even if your scenario is legitimate.
If there is a blind corner you should slow down enough that you can safely stop if there are obstacles in the road. You don't know what's in the oncoming lane, so you can't assume that it'll be safe to blindly swerve into it to avoid something in your lane.
Secondly, lane keeping does not lock your steering wheel preventing you from changing lanes if you need to. The additional force required to override it is the difference between steering with your pinky and gripping the wheel with your hand.
