The Grey Wardens for all their notability and skill are making progress in the deep roads but still can't stop the darkspawn entirely even with the help of the dwarves. The roads are not all mapped and tunnels are filled with more dangers than you can shake a stick at. You guys like being underground so be it that's in character. Gerald sees this as utterly stupid because anyone of us could get infected with the taint and die. Plus the dark spawn may be gone but their traps may not be along with red lyrium a thing that drove the templars, whom Gerald had known as stalwart in Kirkwall, to madness. Why take the risk of running into two of the most lethal things in the area just for the sake of a short cut. 

Maybe they do find stuff of value...and they need to lug it around with them in the deep roads ontop of all the dangers down there. Power and numbers doesn't always win. Gerald is only going down there because he agreed to work with the group otherwise he'd say fuck it have fun running into darkspawn and getting infected you insane group of twats.

At the end of the day Gerald is out numbered in opinion and we're going down there to Starkhaven that's a given. What comes of it may prove him right or wrong or neither. So let's [i]please[/i] drop why I'm siding with Gerald as I don't want to have to explain to everyone WHY he's thinking the way he is anymore because there is no point in trying to do so.
