Escape to where would be the question should one actually manage the feat. Unless they have the intelligence to control Acumen's machines and return them exactly to their own world..."escape" may mean "broadened their containment."
[Itachi looks at this as logically as possible. Even should one manage to escape the prison, they may not return home and they know nothing of the world above the ocean they are trapped beneath. Being stranded on an alien planet is still like being in a prison.]
