Lots of space for floating cloud cities yeah, but wouldn't most people consider creating a floating city 'a bit more difficult' than an atmospheric dome?

Just trying to find the logic with Gas Giants being habitable, on a huge scale, for Rock or Ice planet natives.
I can see it working with 'energy beings' and the likes, something akin to the Vorlons of B5 and such, but making cloud cities to support (alot of) facilities( and several billion people ) appears a little strange. Then again, so does Mineral mining on those 'planets', I guess.
