I think it’s supposed to highlight the futility of the quest.

Frodo was charged with carrying the epitome of evil into the seat of its power while it tempted and tormented you. Not because you think you can, but because it is the only way to actually solve the problem.

In the council of elrond, some of the elves suggest throwing the one ring into the sea, and Gandalf warns that great rings like these tend to be found because they want to be found. They shouldn’t seek a delay, but a final end to the evil.

And the only way to do that is to bring it to Mt Doom and toss it in.

So they do the right thing. They take the ring all the way to Mt Doom and in the midst of where it was made, it is so powerful that none could resist it.

But someone crazed about the ring could be careless enough to fall in. Which is why Bilbo’s mercy was so important. Without Gollum, the ring wouldn’t have been destroyed.

It was because the Hobbits were lawful good to the core that the ring was able to be destroyed.

Putting fiber in the ground is expensive. I work for an ISP, and we estimate fiber overbuild costs at $15/ft. So a mile of underground fiber costs about $79,200.
