> HOW ABOUT we use a lifting body like an airship instead?
It's not immediately clear that a larger airplane would need a larger airport. The size of the runway needed really depends on the minimum speed needed to take off and stay aloft, and how quickly it can reach that speed from a standstill. A huge plane with large, efficient wings and powerful engines that can take off in 5000 feet of runway with a 100+ ton load can still use just about any existing airport.
Meanwhile you can't even get an airship out of its hangar if it's a bit windy, and it's not like a construction site for wind turbines would have any strong wind, right?
