Having advance directives that specify the proper level of care can be easily bypassed by doctors dedicated to advancing the cause of death,. All they have to do is convene an “ethics” committee to vote to stop treatment and give you 72 hours to find another hospital to treat the patient if you disagree. I have seen it happen, and it will become routine.
Australia has futile care policies. It’s not about treatment. It’s about depopulation. It’s no surprise the green movement is for euthanasia. They like trees way more than the human race.
