> A lot of kids have to live by arbitrary rules that don't make any sense, or if they do, haven't been explained to the kid.

Yes, and that’s what all humans experience throughout their whole lives.

If kids aren’t exposed to measured loss and frustration in the thoughtful safety of their home, they won’t develop the skills needed for adulthood, where loss and frustration may not be so measured and constructive.

While lying is one coping skill they might develop, there are many others, and a helping role of the parent is in helping the kid find good alternatives.
