Actually, it's not that I'm uncomfortable with advance requests; I'm more uncomfortable if there isn't an appropriate mechanism. The fact remains that an advance decision isn't made on the spot; it's a decision that people make, as best they can, in advance of a situation, based on the knowledge at their disposal.
I don't think I'm qualified to judge whether its appropriate to expand access to medical assistance in dying. If that's where we now stand, and a large segment of society thinks it's a good idea, that's fine. However, I think there'll have to be a lot of guidelines and support measures.
My studies focus on consent, individual autonomy and relational autonomy. You have to understand that decisions aren't made in isolation. The decision or wish to receive care, for example, is part of a dynamic that includes caregivers and family members.
