Yeah, it's not very efficient. They only need one tree to get faith from it.
Though the bonus does double if you have 3 or more. So, you could pretty easily *weaken* their ability.
...but who wants to waste time depriving another civ of 1 faith/turn when that worker could be doing better things?
Edit: Also, from now on whenever I play against the Iroquois, I'm going to strategically chop a few forests to deprive them of their trading routes. Mwahaha.

Well, that requires quite a few turns to chop all the trees or else the Celts might just move slightly to still capture them. It's much easier with the Iroquois to create essentially a "fire break" in their trade network by cutting on or two forests as opposed to all of them.
Personally, I'd rather use my worker to build a farm or mine instead. Seems a much better use of my time.
If you wait until they build the city, why not just conquer the city? I agree with the latter. That's what I'd do.
