An airship's lighter than air nature is one of their biggest drawbacks. An airship needs a large volume in order to make all of its heavier than air components lighter than air in aggregate. This makes for a huge sail area. So even modest winds make it difficult to control an airship near the ground.
When an airship is near the ground it doesn't really land, it moors. Even if it compresses or vents lifting gas to control buoyancy it's still a giant sail very close to the ground. A gust of wind can seriously damage the airship or mooring or cause it to spill cargo or passengers.
I love the idea of airships but they have a huge number of practical concerns.
