Honestly, that's how I view it. @
Lanefan's "breaking in period" makes sense to me.
Yes, I would view it that way. Chaotic good gets the pass because, well, being good, the character still values the life and well being of others. Think Wolverine from the X-men. Disobeys orders, often goes off on his own and is frankly a menace to the team, but, generally well intentioned and often acts in other character's best interests. A Chaotic Neutral? Why on earth would I want that on the team? The alignment is diametrically opposed to everything that a team represents.
For one, following the laws of the land is not what lawful good is about. Lawful Neutral? Maybe. But, the good aspect of LG means judging laws based on morality and acting accordingly. What about LG would imply that they have to follow all the laws?

And, @
5ekyu's idea of whims. You own definition states that whims are illogical - they cannot be explained.

Lastly, it's this whole "well chaotic can be just as reliable as lawful" that has made demons in D&D unbelievably bland. 3e was particularly egregious for this. Demons that have deep, methodical plots that involved many parts? What? Naw, you're the thing of raw chaos and destruction. Plans are for weasel tongued devils. You're a demon. Live the life.
But, no, we get demons like Malcanthet and whatnot who are basically just devils with different damage resistances. BOOORRRIIIINGGG.
If CN is functionally no different than LG, then there's no point in having alignment. If a CN character is just as reliable and dependable as a LG character, then why bother having alignment at all?
And, honestly, if you want to play a reliable, dependable, works well with others character, why is it a huge problem for that character to write Lawful Good on the character sheet? What changes?
