I will have to disagree, Gordis, Men knew full well that an enchantment lay on the Rings, and they used them quite readily to gain wealth and power, and through avarice and lust for dominion Sauron entrapped them.

The Nine Men knew it were Elven Rings of power and thus surely enchanted.
What they didn't know was that the Rings were corrupted by Sauron and that he possessed the Ruling Ring, thus gaining access to their thoughts and their souls, while they wore the Nine.
The Elves made the Rings for themselves and were eager to use them for their own ends - to "embalm" things, to prevent fading etc. Had the Elves used them, they would have been entrapped in the same way as the Nazgul. What prevented them from using the Rings was only the knowledge of Sauron's treachery: the Elves took off their Rings and didn't use them in the Second Age because they knew it was perilous while Sauron had the One. Men didn't possess such info.

As for intentions, it is clear that at least some of the Men had been well-meaning from the start:

‘A mortal, Frodo, who keeps one of the Great Rings, does not die, but he does not grow or obtain more life, he merely continues, until at last every minute is a weariness. And if he often uses the Ring to make himself invisible, he fades: he becomes in the end invisible permanently, and walks in the twilight under the eye of the dark power that rules the Rings. Yes, sooner or later - later, if he is strong or well-meaning to begin with, but neither strength nor good purpose will last - sooner or later the dark power will devour him.’-The Shadow of the Past, LOTR

Actually it shows that between Dwarves and Men, Men were more easily corrupted, while Dwarves proved practically immune to the Rings. Thus Men got weaker Rings and more rings than the Dwarves. Here is the whole quote:

But Sauron gathered into his hands all the remaining Rings of Power (that is the Seven and the Nine]; and he dealt them out to the other peoples of Middle-earth, hoping thus to bring under his sway all those that desired secret power beyond the measure of their kind. Seven Rings he gave to the Dwarves; but to Men he gave nine, for Men proved in this matter as in others the readiest to his will.

As for "snares of power" etc. we know what certain Elves and Maiar are capable of...

Likewise, it is evident that Men used the Rings as tools to increase their wealth and power, and that Men were quite aware of the abilities the Rings bestowed; however, it is also plain that, like any other addict, they ignored the painful side effects, and blithely went on using the Rings without concern for consequences. They may not have been aware of the end result, but they certainly would know the toll the Rings were taking.

Once they started using the Rings it was next to impossible to stop: that was the whole point of the snare. And Sauron, gradually working on the Men's minds through the One, succeeded to corrupt them and to change their mentality, so their good purposes didn't last long. But had Elves or Maiar been in the Men's place, it would have happened with them as well. None was incorruptible, even Dwarves (to a certain extent). Gandalf feared to take the Ring himself, as did Galadriel, just because they knew that.

He didn't. It is a hypotheses I have advanced in my first post. Neither did Tolkien write that ALL the Rings were associated with Elements. The Three were - but what about the rest? It is being discussed in this thread.
