The space-based portion will not need to support itself against gravity (other than relatively weak tidal stresses).

I've studied the tidal stresses the Raft will undergo at closest approach.

Pluto's surface was geologically complex, here at this point of maximal tidal stress.

The station was deformed by the tidal stresses of the wormhole's immense gravitational well.

Fortunately, the tidal stresses cause nearby dormant volcanoes to become active again.

No, the tidal stresses would tear it apart.

Anything falling into an event horizon would be torn apart by the tidal stresses long before.

You don't have to have water to have tidal stresses.

Le Havre marina accepts boats 24/7 without any tidal stress.

There'll be tidal stresses to crack the planets and let out their internal fires.
