It does not violate Tower Law, merely offends the sensibilities of women for whom this is none of their business.

That is the punishment Siuan speculated would be given out by the Hall "...making them pass their warders to others, since they like it so much." Myrelle, Nisao & Siuan all felt it was a credible threat.

So were Hitler, Stalin, Linin, Mao & Castro. Your point being?

It was the fault of the Germans that they elected a loose cannon psycho as Chancellor and passed a law that let him become a dictator. Does that give Hitler the right to do whatever he wants? What is wrong with Egwene being a puppet? What is wrong with the Aes Sedai being governed by the Hall, whom they directly chose for their experience or other qualites? Why should they be governed by a woman most of them would never have chosen? The principle of democracy suggests that a leader controlled by the people's elected representives is better than a dictator with undefined powers, whose level of authority depends on the political weight she can appear to weild! The whole point of the rebellion was to oppose a stron Amyrlin. All this idea that Egwene is owed Elaida's level of deference does is reduce the Tower struggle to a contest of dictators. Think of the situation objectively, not through the personal satisfaction of a PoV character.
