There are a lot of escort events, especially in lower levels zones like Kessex Hills. Escorting Doylaks and merchants between outposts are very popular events with players and I enjoy them even on higher level characters. But why don't these guys use waypoints? Waypoints are part of the lore, they also cost to use (though not for the player). I don't think it can be explained as "the cost is too much" because merchants would actually be quite well off.
