Because, if you are good at last hitting you can get 15 creeps in 3 waves. You are never guaranteed to pick up a kill, and it is significantly more dangerous (jungler counterganks, pink wards). Farming is just safer and will net you much more consistantly high results. Not to mention roaming means that you leave bottom trying to 2v1 which will result in them getting zoned.

Jungle twitch is a different story, you want to put more effort into ganking than farming since killing monsters takes forever with twitch.
