It's not that bad an excuse. Although I would welcome stacking logs and ores, events like voidwatch and woe drop so many materials that if those were stackable they would flood the market. Right now, people just destroy them unless they are a crafter and carry crystals.
Perhaps HELM activities could be updated though, to make it more appealing... tool dispensers, high level harvesting gear (ideally obtained through harvesting items to make said gear), better and update drops, etc.
