As the article notes, goods would move a lot more when they're subjected to the G-forces of a hyperloop than the occasional rolling of a ship or even much milder G-forces of an aircraft taking off, which they have to be packed pretty carefully for as is. And whilst all transport methods have a weight limit and some degree of load-balancing requirement, it's much more of a restriction for the load of a capsule fired at supersonic speed through a curving tube that has to resist forces imposed upon it than a bigger lorry chugging along at a sedate 60mph.
