I explained earlier that getting around the Death Star wouldn’t be that restrictive.
If you could take away the obvious barriers to making one (the ones they ignored in the very silly Total Recall remake) a gravity train would go pole to pole through the Earth in about 40mins.
The Death Star has lots of elevators and lifts which could act in the same way, it’s not the size of the Earth and it exists in a universe where artificial gravity is cheap enough for smugglers to have.
The same would probably be true of the base.
