If you read what I wrote, then I was saying that particularly this one was probably coming from the Ring's power.

If you are suggesting "Finrod was a loser", then I have to strongly disagree. His contest with Sauron was not some stupid loss, quite the contrary, I believe we can sort of compare it to Fingolfin vs. Morgoth. Or Gandalf vs. Balrog when he was closing the door to Chamber of Mazarbul. And I doubt you would call Fingolfin a loser.
Nevertheless, what you said, for example the "reading mind" thing, does not need to have, I think, anything in common with the Ring itself. Quite the contrary, I think it's exactly the example of how powerful she was. After all, Galadriel is mentioned as the most powerful in mind right after Fëanor, and that's exactly what you see here. And yes, Finrod was therefore probably not as powerful as her - as all the Elves (but he was not a loser).

But then she also asked Frodo, "Did not Gandalf tell you that the Rings gave power according to the measure of their wearer?" -- which can only mean that the Three also enhanced the innate strength of their bearers. And Galadriel, being a powerful elf, would access to much of Nenya's powers, right?

Just one note before start - Galadriel, as neither of the Elf lords, was not able to use the power of the Ring openly. Just rhetorics, I know - but let's not confuse it.

Okay. Now to the main point. What the Three do I already mentioned in the post before where I quoted Elrond, and I'm not going to return to it, it's all there. Just your claim now does not in any way contest it. The words "Did not Gandalf tell you that the Rings gave power according to the measure of their wearer?" mean no more and no less that the Rings give less power when a less powerful person wields them, greater power when a more powerful person wields them. Less powerful person can make a mosquito flee away from him, more powerful person can stop the Ringwraith. But it does not, as you deduce, based with no evidence, enhance the innate strength of their bearers. Galadriel, being a powerful elf, would access to much of Nenya's powers, right - that's okay. But these powers are for making, healing... whatever. Nothing about boosting own powers.

Lórien is something else than Rivendell because a different person is it's - let's say, ruler. But surely you don't say that Rivendell didn't have its own atmosphere? It had, just a different one. I don't actually understand what are you going to say with this. The only difference could therefore stem from the Ringbearers' attitudes and personal aims. If for example a Balrog had an Elven Ring and wanted to use it to preserve his own realm, it would have also a different atmosphere: let's say burning fires and everlasting darkness. If the Witch-King did something like this, his realm would have been a moonlit freezing place full of fear. The same it is with the Rivendell-Lórien difference.

I believe that surely she would be able to face the balrog, but because of her own strength in battle (whether physical or spiritual), Nenya has nothing to do with it. Galadriel could shroud Lórien in mist with Nenya to cover it from the Balrog descending from the mountains, but in battle, the Ring won't help her much. It was made for understanding, making, and healing, to preserve all things unstained - and surely nothing of that could be of any use in a duel.
