On the face of it, your point is valid, just like on the face of it landing rockets is too complicated. Both are likely solved the same way - active management by responsive computers to negate environmental effects to behave in a stable manner in an unstable environment. This idea certainly wouldn’t have worked 100 or even 50 years ago, but may be quite possible now.
I think it makes way more sense for airships to be anchored down while loading and unloading, so the buoyancy doesnt need to be constantly balanced.
