the holodeck is a localised system and a relatively small location, life support covers the whole ship and is probably quite energy hungry.My point was that if there was such an independent power source and we buy either of the reasons given for running the holodeck on it, then why not life support as well? Life support trumps doctors and psychological comfort.
Also, it was not really necessary in this episode, but we’ve seen in the past that’s totally possibile to cut life support only in certain decks.
