as being a nearly perfect visualization of what the unforeseen results of the use of a source of power that doesn't belong to one might be. Gandalf's statement to Frodo reinforces the warning: ..."Do not tempt me with this Ring! I would use it from a desire to do good, but..." And, of course, Frodo's final failure at the mountain of fire shows it even more clearly, that even someone unwilling to use the Ring would be overcome by the lust it inspired, if in possession of it for too long. The subtle implications of armor on Galadriel are that even a Lady whose life was dedicated to creation would yield to the lust for dominion by force. I don't think anything else would have conveyed the warning more clearly, or made Galadriel's victory in refusing the Ring more apparent. Whoever wrote that disparaging comment obviously didn't get the message...
