We have to assume that the very experienced ITU doctors, and the various judges involved, would move him to a hospice if at all possible.
If they move him as he is with all the equipment, how are they to find sufficient staff to cope with the equipment and to then facilitate the withdrawing of it in a hospice? There are some hospices that accommodate residents with ventilators, usually those on them long-term who come in for respite for their families for a period of time.
Life support is much more than a ventilator. When support is removed highly skilled staff have to be at hand to deal with the consequences - unfortunately when things are 'switched off' it doesn't always result in peaceful slumber then death, things can get distressing and action is needed to prevent/alleviate this.
I don't why people think it's all so easy.
