While I agree wholeheartedly with what you're saying, it does seem like you're underplaying the gank aspect a little too much. Being able to feign being weak or overextending to bait them to jump in for the kill while the jungler is ready in the bushes can be quite powerful. A team with a jungler also tends to have a little bit more map awareness/knowledge than one without a jungler.

You also left out buff control. While not as important as dragon, keeping the enemy's red and/or blue buff away from the hands of their carries (red) or support/mage (blue) can really put a throttle on their ability to get kills or farm for gold.
