It unfortunately scales up very well, or rather it completely doesn't scale down. The problem is while gigantic design seems to be good on paper you can't build

It unfortunately scales up very well, or rather it completely doesn't scale down. The problem is while gigantic design seems to be good on paper you can't build a demonstrator blimp or a small scale model (kinda like airplanes can with widebody/narrowbody or shorter/longer fuselages) to break into the commercial industry. And they need not only individual scale of a single ship but also quantity scale to show that they can operate profitable. And even if someone build them, then they need to convince people to switch from ships, trucks and trains. And places unreachable by those already don't have enough production for the gigantic blimp transport. But it would be awesome if someone goes full Elon Musk on this idea and bruteforces the final giant design with a pile of money. Blimps are great :)
