Programming children would be coercive.
The whole point would be to create a social enviroment to which the only reaction possible is ethical. Where attempting unethical behaviour would be like considering spooning out your own eyeballs. Technically a possibility but but but why would I do that…?
Maybe the ‘auto-get-into-shape-house’ is a better illustration.
You’re fat. You do not like this, nor does your significant other. But jeeze. The gym is so far away, and the fridge so close.
One night, I come to your house with my team of crack ethical architects. I remove the stairs, and put in a climbing wall. The corridors and halls between rooms I replace with pits and monkey bars. The fridge is a bankvault with a timelock, and instantly disintergrates anything not containing enough fibre to stun a moose. The TV runs off a static bicycle for power. And your internet connection speed is linked to how fast you can run on a treadmill. The bathroom moves to always position itself at the furthest point from you in the house.
Now, you will either become thin, and fit, or wallow starving in a pool of your own waste. But there is no coercion involved - simply how you decide to react to your enviroment.
