Nenya or the Elessar?

[Gorthaur the Cruel]

Her statement that she wished the One had remained lost can be explained by her having regret that the party had to end so soon, and in such a fashion: because it had been found, she knew that one way or the other she would finally lose all she had gained by the use of Nenya.

I don't understand what you meant by this, as you previously stated:

it [Lórien] was a hollow echo of the true immortality of the Undying Lands, and someone like Galadriel, who had experienced the real thing, would have perceived that.

What "party" was there or "gain" to be lost if Galadriel pereceived, as you said, all that she created with Nenya to be a hallow echo of the West? It just seems incosistent to me for her to regret creating everything with Nenya in the line of thought that it could never be as good as Valinor. I got the impression that she was quite satisfied with all the things she accomplished with Nenya and her very own version of Eressea in Middle-earth. So if her joy is diminished (when weilding Nenya & enhancing Lórien), why is she lamenting over its inevitable demise? It's contradictory if she's regretting it because all her endeavours pale in comparison to Valinor. Otherwise, why her deep love for Lórien if it was a half-assed Valinor? But if she regretted using Nenya and all that she wrought with with it because it must come to an end (being bound to One's power, her refusal of the One, and subsequent aiding of the fellowship), then that's more feasible.
