I mean, your example is literally spot on. You as a parent can't be objective - you have to oppress your children to get them to adhere to your ideals of the household.
* having expectations involuntarily set on your performing of activities that you would not voluntarily perform otherwise;
* punishment for failing to meet those expectations, rather than a reward for meeting those expectations
With the contradictory idea of the person setting the expectations and punishments being "objective" in a discussion.
Certainly if the request from the children is "we don't want to clean our rooms", the only truly objective response is to either:
a) incentivize them to clean their rooms with negotiated rewards and benefits, in a true market sense b) convince them through logic and rhetoric to voluntarily choose to clean their rooms; c) agree that they don't have to clean their rooms.
