I'm not so sure the Fair Folk's traditional aversion to iron symbolizes the conflict between nature and human progress. It's old, old lore, older I think than that conflict has existed in the popular consciousness -- it's hard to see how some Pictish goatherd nailing a horseshoe to his lintel is thinking in terms of science and technology. And iron was also supposed to repel evil spirits, bad luck, and witchcraft, which are not so obviously "nature bonded" (though for that matter, I also question how much fairies represent "nature"). Iron seems to be best understood as repellent to magic, whatever the source.I believe the druid’s restriction on metal armor has similar meaning as the fay’s weakness to iron: it’s symbolic. Metalwork is a symbol of progress, science and technology – changing nature. Fays were, basically, weak to man’s advancement as "nature bond creatures", and druids are nature priests: therefore, adversaries of technology – changing nature.
