The nomad ending is kinda hopeful but they don't have the tech, resources and clout to actually save your body either. Plus they've already proved they're incapable of saving you completely.
They wouldn't want you to steal from it, or need you to investigate it. Plus doesn't Arasaka have something to do with the casino? Like the security or an ownership stake in it or something. You fulfilled your purpose of bringing back the biochip so they can resurrect Saburo and in your broken mental/physical state you aren't of any use to them as a special agent.
Arasaka doesn't care about you anymore in their ending. Only the blue eyed man way would make sense, at least in my mind obviously, of giving you hope of saving your body in the future.
