You (correctly, I believe) distinguish between controlling the reward function and controlling the rewards. This is very important as reflected in your noting the disanalogy to AGI. So I'm a little puzzled by your association of the second bullet point (controlling the reward function, which parents have quite low but non-zero control over) with behaviorism (controlling the rewards, which parents have a lot of control over).
