i don't know, i imagine a universe where there are large blobs of just water in space, and guys like this scavenge them, from space ships that accidentally fly through them. cuz they are space ships, not submarines.
Seems legit to me. I imagine in the far future we would be in space with the same kind of ships to a submarine and space suits to an old bubble head scuba suit. This is an awesome design for the concept. Even the prosthetic arm
Hmm! Air and water spheres show up in some of Iain M. Banks' writing, but I don't think they get focused on particularly beyond an apocryphal story within The Algebraist.
