[Warcraft] So if mages can teleport stuff and people from place to place, why are there even dock-workers and stuff?

I mean, why not just teleport all your supplies magically? Make a portal from Westfall to Stormwind to move your grain, then from Stormwind to where ever people need food. It can't be robbed, it won't spoil... Seems like there's no downside.

Does this actually happen or does it not? Any particular reason why?

Mages are not really common enough for that. It seems like there are a lot because a lot of players (and NPCs players interact with) are magic users, but remember that the player characters and their associates are already exceptional. Only a small percentage of the overall population can use magic. Even among those that can, not everyone who can use magic can teleport or open portals, and not all of those can do it particularly well or for an extended period of time.

On top of that, magic users are in high demand in other areas. Magic users are needed to fight in the various wars, or to perform important rituals. Their talents are frankly too powerful to be wasted on something that can be done, albeit more slowly, by a team of horses. Every mage that is maintaining portals to Westfall is a mage that is not unleashing their power against the Burning Legion.
