Placebo effect and other theories

[Encaitare]

Enca as well thank you for your thoughts and in response is it possible he wanted frodo to continue to believe the ring was all powerful ans is it possible tom and goldberry planned on guarding the brooch..

Again, I don't think so:

"...He [Bombadil] is a strange creature, but maybe I should have summoned him to our council."
"He would not have come," said Gandalf.
"Could we not still send messages to him and obtain his help?" asked Erestor. "It seems that he has a power even over the Ring."
"No, I should not put it so," said Gandalf. "Say rather that the Ring has no power over him. He is his own master. But he cannot alter the Ring himself, nor break its power over others. And now he is withdrawn into a little land, within bounds that he has set, though none can see them, waiting perhaps for a chnage of days, and he will not step beyond them."
"But within those bounds nothing seems to dismay him," said Erestor. "Wpi;d he not take the Ring and keep it there, for ever harmless?"
"No," said Gandalf, "not willingly. He might do so, if all the free folk of the world begged him, but he would not understand the need. And if he were given the Ring, he would soon forget it, or most likely throw it away. Such things have no hold on his mind. He would be a most unsafe guardian; and that alone is answer enough." [Italics mine]

A somewhat lengthy quote that's probably been referenced a thousand times before, but it still works to explain Tom's nature. Unless there is a very different side of Tom that we're not seeing, the fact stands that he's just completely disinterested in matters outside his neck of the woods. And perhaps the "bounds that he has set" don't only apply to the physical area, but also to bounds he's put on himself. Maybe he has more power than he's letting on, but just doesn't care to use it. I don't think he wanted to trick Frodo. Despite all the confusion he gives us trying to figure out who/what he is, he seems like a simple sort of being at heart, who just wants to go about singing and rhyming and gathering flowers. Not a bad life, I think.

so therefore it is possible entwives are not lost merely treeish?

That does strike me as possible. But Entwives also seemed like they had more of a drive or purpose when they were on their own. They were happy to tend the earth and do whatever Entwives do on their girls' nights out. The Ents, on the other hand, became somewhat lost without their female counterparts. It seems to me that the Ents would be more likely to become treeish because of that.
