Sorry, the italicized point you made above isn't invalidated were he to have either demoted her, or sent her to Mithila (incidentally, how would being sent to Mithila - her parent's home - have been any more shameful than sending her to a stranger Valmiki? Rama wouldn't have been indebted to Janak, but he certainly ended up indebted to Valmiki). He had already decided to strip her of her title as queen - that happened automatically when he sent her to Valmiki's ashram. Had he done what I was 'suggesting', the people of Ayodhya would still have gotten their wish - Sita wouldn't have been queen - but at the same time, Sita would still have had what she always wanted - the company of Rama. She wouldn't have been in sight of the people - there were private quarters in the palace, and the prople who resided there weren't there in full visibility of the people at the Ayodhya court, the way Maharani Sita was. By doing this, Rama would have fulfilled both his duties as king (by removing Sita as queen) and as husband (by assigning her to Kaushalya, she would have had his company whenever he visited Kaushalya). Remember - Sita didn't care for royal titles, and would happily have sacrificed that title had she been allowed to continue to serve her husband in some capacity, shorn of the luxuries.
In fact, here's a counter argument one can make. Kaushalya belonged to Rama. Janak belonged to Sita. Had Rama sent Sita to either of them, he'd not have been putting himself in debt on anybody. But by sending her to Valmiki, he made his entire family indebted to Valmiki. Wouldn't it have been better if he had kept her within the family, sans the Ayodhya maharani title?
That last part is incorrect - as Mando pointed out, the people never accepted her chastity, even after she took the vow. Rama accepting his kids without unconditionally accepting Sita was not understandable: either he publicly repudiated his subjects on Sita's chastity, in which case, his desire for his kids was acceptable, or he publicly accepted the unstated desires of his subjects to see that proven, in which case, his desire for the kis was unacceptable. Also, note that not all Suryavanshis had their eldest succeed them, for varying reasons, and it was one that Rama himself didn't really care for. That explains why he was too happy to give the kingdom to Bharat when it was desired of him, and why he left Bharat as yuvraj even after he got back his sons. In fact, after the demise of Lakshman, he first offered Bharat the throne. He should have pre-forced the issue by having Kush and Luv installed in their own kingdoms after Chandraketu and Angad were, and then gone through this process of seeing Ka'al and Durvasa.
The other evidence that Rama didn't care too much for this tradition of the eldest succeeding the throne was there in how he himself acted - not only did he force Shatrughan to become the ruler of Madhupura, but he had each of his nephews installed in kingdoms of their own, and even had Luv crowned. Had this been such a sacrosanct tradition, Rama would have crowned Kush the emperor of his kingdom, and had all his brothers become his courtiers and followers, instead of creating 7 more dynasties.
