This is the viewpoint I have basically had shoved at me about lawful good in practically every morality and alignment conversation I have ever had, so I find it really common. Lawful good is apparently for fanatics and people who love any excuse to be rigid and controlling (and you can't tell these people they are acting more like lawful evil.) Neutral good is much more benevolent and willing to listen to reason.
As they say, the law is harsh but it is the law! It’s not my bag, personally, but I think it makes perfect sense that the good alignment spectrum makes space for a view that sees order of so much importance to producing good in general, that rules should be adhered to even when they lead to undesirable consequences in some specific cases (EDIT: within limits, as I’ve just seen mrfuji3’s post convincingly arguing).
Though I am with you in not thinking alignment should have any mechanical significance within the game.
