Isn't that what I proposed in my example though? Where a rule is made in advance that if the player abuses their power, they die. due to the canon situation in which that player's character existed?

A player that in good faith wanted to role play such a character, would work with the DM in advance to structure rules well-understood by all parties about exactly what would happen if they abuse their situation.

All the DnD situations can be trivially resolved by good-faith and communication on all sides.

Unlike Chat Control, where good faith cannot be assumed.
