I’m not really clear on why the turbolift would fall in the first place… Is that a gravity plating thing? I guess gravity plating must work without power?
Also Picard knew it was going to fall… are we to infer he’d rather be pancaked than spend another moment with those kids?
So that you can stand on the lift, and not get head trauma every time you want to travel to a lower deck I’d assume.
You would just generate gravity in the lift pod itself.
