I think it's time for the infinite oregano argument to re-surface
I found an awesome loophole! On page 242 it says "Add oregano to taste!" It doesn't say how much oregano, or what sort of taste! You can add as much oregano as you want! I'm going to make my friends eat infinite oregano and they'll have to do it because the recipe says so!

Whatever the ruleset, if you and your players decide to find a loophole, i'm confident you'll manage to do it. This isn't a simulation so it's especially true for D&D. If you want further examples of how the RAW can be abused, refer to the bag of rats trick where you carry a bag of portable creatures such as rats that you take out and kill with powers when you need to gain bonuses triggered when you kill a creature (bet you're happy that i just told you 'bout that one, aren't ya?

); or to wizards using some spells in 3E to upset entire economic systems.
If you want, as a DM in 4E, to allow a wizard to take down entire forests with his magic missile, more power to you. If a wizard in one of our games were to come up with that, i think everyone around the table would just look at him with raised eyebrows and continue as if they hadn't heard anything
RAW aren't the bible, they're rules to be used as part of a heroic fantasy game. The reason why magic missile is an at-will power (and thunderwave, yes!) is so that wizards can deal as much damage as members of other classes that use weapons every round, during heroic fantasy battles. If that's too far from simulationism for you, then perhaps D&D 4E isn't the game for you.
This being said, technically, if you really wanted to drive your point home, you'd use a stricker as the better example. Indeed, a ranger can deal 2d10 damage per round with the at-will twin strike ability, much better than the meager 2d4+INT from the wizard. Taking down forests with bow and arrows, now
that would be a feat! If you still insist on magic, the warlock would be a much better woodcutter than the wizard also.
