My point is that we don't know how much it would cost, and they're probably quite dramatically different amounts for each person. We should put in the effort to find out, and then make sure that the costs are paying for services and that the services are delivered, so that those individuals can have full and wholesome lives.
My key point is that we cannot say we're going to do something, but we're not going to pay for it, and we're going to bring people in who are going to have miserable lives. We want to bring people in to have full and wholesome lives, which means there are costs and we need to pay them, or there may be costs. We should figure out what the costs are, and assuming that there are some, then we need to pay them.
