Okay fine, I forgot about fishing and all that... but for the orchards and crops, who would tend them? *interesting image of random elf on a tractor in overalls* They would have to manufacture their own implements, and though a shovel of mithril would have been pretty, it's kind of impractical. Though it would get me to tend my garden more. Is there any record of a mundane object made by elves? I know they were good with precious metals, and they could make weapons and jewelry, but were there any not-so-romantic tools made? Or did the elves just keep that under cover to be more impressive?!
Also, forest crops get kind of limited after a while.. But since the gardens of Lorien are supposed to be magical, they would probably be able to manage it.
EDIT: hey... 200th post!
