There are forrests of gigantig trees and your crops or lifestock live

over the forrest, lasso strong enough branches (insert some biobabble
why strong branches stick out far enough to be lassoable) and then
enter the tree crown.
You can't get there with ground vehicles, you definitly can't use
planes. Optionally you can add a technobabble reason why grav vehicles
disrupt the ecosystem, or have a local superstion that says so.
In a forest canopy, compact and agile grav flyers should beat huge
airships. And I'd rather not work with superstitions.
At TL6, a blimp is much cheaper than a rigid airship. A rigid airship
must be sealed, at $40/sf, while a gasbag is $0.005/sf. On the other
hand, gasbags are limited to good streamlining. That means slow, local
use LTA craft are much cheaper than fast, intercontinental ones.
750k gasbag, 25 stons, drag around 18k, two 1 MW props, HP gas engine,
50 mph, fuel for 20 h at 30 mph = 600 miles. I'll have to look at the
numbers, but it might be 10 people and 5 stons payload.
That's more power, less endurance, less speed than a historical blimp,
probably because of the streamlining rules.
