Locavores do more harm than good?

Now I admit I have some biases, and my biases are that the locavore back-to-nature stuff is a luxury obsession for people who can afford it.  You may already know where this link has been discussed in other places and if so I won't repeat all that.  Seeing as I live in Seattle it's impossible not to run into people with locavore ambitions.  It's something that people who would otherwise never associate for political or religious reasons can actually agree on in this town.  I don't happen to be a locavore myself, though.  Some food being local is great but I'm for imports, too.
