If you don't have enough reaction mass (for which water sometimes qualifies) to get out of orbit, having air but no water (rather than water but no air) just me

If you don't have enough reaction mass (for which water sometimes qualifies) to get out of orbit, having air but no water (rather than water but no air) just means you die three or four orders of magnitude more slowly. Maybe someone can lauch a rescue mission within a matter of days, but given how slow most space programs move these days, I'm not optimistic.
