If something doesn't exist, especially when it's something that has existed in the past but no longer does, there's usually a good reason for it. It's not a natural law, but it's a good rule of thumb to use to initially question and defend a "groundbreaking" idea. A quick search online tells me that ocean freight is about $1.3/lbs and air freight is about $5.3/lbs. Since we already know that "airships" would likely never be more convenient than existing air cargo, their only way of succeeding is if they found a place between 1.3-5.3 where the cost savings felt motivated to sacrifice regular air freight, while being many orders of magnitude better than ocean freight for that use case. Even if we're nice and call this a "new" technology rather than what it actually is -- a tried and failed technology -- this "new" technology needs to be many times better than existing options either for cost or convenience (preferably both) to offset the major penalty you will have initially due to the lack of existing infrastructure; and we're not just talking about airports and runways, we're talking about the entire network of optimizations in logistics, maintenance and everything else that have occurred during a century of practice. I'm just a guy with an opinion, but I very much doubt cargo airships even have a small chance of being "big", unless someone builds something absolutely groundbreaking that leapfrogs existing air cargo solutions entirely -- for example in areas like fuel efficiency, autonomy, or something else. Nothing is impossible, but if I was a very technical and entrepreneurial person, this isn't where I would put my time.
