Confining people so that they cannot leave is our primary form of punishment. We're so horrified by it that we wrote it into the Constitution that you can't be deprived of your liberty except by due process of law. Even if the conditions are pleasant. (Prisons aren't supposed to be cruel, though apparently we've decided to tolerate that.) It does sound compassionate to force them into a place with a bathroom and a door, but if they can't go see their families, look for a job, or go for a walk, maybe it isn't as compassionate as it appears at first glance. (And that is on the assumption that the facilities are less unpleasant than our prisons. I strongly doubt that.)
